In this section you can download the latest manual and executable.
Without a valid license key the software can be used in demo mode, with restrictions.
For evaluation of the full functionality you can request a 4-weeks trial license . Please use your official company, school or university email account.
- fixed: using absolute angle or length of a Curved slider as argument in the force vector table resulted in incorrect forces. Also the warning message was inconsistent.
- fixed: using absolute angle as argument in the force vector table could (under certain conditions) result in incorrect forces. Also the warning message was inconsistent.
- fixed: the warning symbol "! ! !" concerning an incorrect range for the force vector table sometimes was drawn in a black rectangle.
- fixed: in some cases the menu choice "Loads > Modify" resulted in the popup of the force edit dialog unexpectedly. This should happen only when there is just one load defined.
- update without functional changes.
Release 8.0 (new per 2019-08-26)
- introduction of motor element.

- dynamic construction aid.
Please visit the Download page and retrieve the manual. The introductory chapter describes the new features in detail.
- fixed: using "angle" in user expressions for Beam and Slider resulted in false values when also applying the "length" in an expression. In that case "angle" values were replaced by the "length" value.
- fixed: Gravitational forces in slider element not taken into account.
- fixed: Analysis performed in case mechanism is statically overdetermined plus simultaneously kinematically indeterminate.
- fixed: User defined expressions (formula's), opening the formula editor dialog resulted in an unexpected ending of SAM in some cases.
- fixed: Results, values of mechanical power in gear and belt were zero.
- fixed: Nodal forces, moving nodes showed wrong values in some cases. Bearing forces of neighbouring elements were correct.
- fixed: Optimisation using Path, a non-fatal crash occurred when using a path of 2 points only.
- fixed: Export Results in SAM Motion Format, units and scaling was wrong in some conditions. This format allways exports SI-rad units.
- fixed: Export Results in SAM Motion Format, the list-preset showed too many checked items sometimes.
- fixed: Export Results, the items-list sorting did not work correctly.
- corrected: Element Properties dialog some German text was cut-off.
- fixed: symbols for English dimensions concerning Force related items [lbf, pound force] were named wrong [lb, pound].
- fixed: Optimisation-objective could not be defined in special cases: after deletion of Element Nr 1, and next creation of an angle fixation.
- fixed: Reference curve for Optimization displayed a constant value of 0.0, when applied to angular properties of a Beam.
- fixed: After using the Optimization dialog, and exiting by Cancel, the Graph was not displayed anymore.
- fixed: Reference curve for Optimization can be removed (=hidden) by the regular toolbar item for removing curves from the Graph.
- fixed: Undo-action did not respond at the first click, when previously an Element was deleted.
- fixed: license activation for business networks is automated now.
- changed: from now we call the "Build" number "Revision". This number is moved from the 4th digit to the 3rd digit in the file properties. The 4th digit is the so called private build number.
- fixed: when using an alternative x-axis property (not Time), the label values for the x-axis were wrong. This only happened during animation, not while moving the cursor over the graph.
- fixed: after changing the property of the Graph X-axis into a nodal property ( position, displacement, velocity etc.), the graph of angular curves ( i.e. angle of a beam) was incorrect. In some cases the curves turned into a constant value of the initial angle of the beam.
- new: at startup of a Floating-license SAM session, while creating a connection to the server a popup message is displayed.
- fixed: the Statistics form showed a wrong file version number after creating a new mechanism.
- fixed: Classroom kit installation with a license server resulted in connection problems ("Duplicate user not allowed"), when using cloned PC's.
- fixed: the Demo version of SAM could not open files from previous versions.
- fixed: the properties of the rotation spring showed faulty units for the stiffness value.
- fixed: a user expression shorter than 3 characters resulted in an unexpected error.
- fixed: the properties of the rotation damper showed faulty units for the damping value.
- fixed: exported angle of rotation elements showed faulty units.
- fixed: the hodograph of a pure vertical movement was not displayed.
- fixed: graphic lines that exactly coincide with mechanism elements were not displayed in the initial position when the display option "hiding mechanism" was active.
- fixed: Start-angle of a beam was changed after addition of a Rotation Sensor, or any Rotation Element.
- fixed: Userdefined Expressions: data of Rotation Sensor were zero.
- fixed: Rotation.Sensor display of angle graph showed unexpected start values.
- fixed: Results > Export of Motion format file resulted in unexpected error message.
- fixed: Userdefined expressions did not handle information of the Rotational Sensor properly.
- fixed: Rotation angle of all rotational element types had a wrong sign under some conditions.
- fixed: The start-angle of all rotational element types is wrapped now between -180 ... +180 degrees
- fixed: Input Motion dialog: clicking the most-rigth column resulted in a table scroll to the left that could not be undone.
- fixed: Input Motion dialog: while in the "Cubic spline" Tab, the same problem occurred.
- fixed: Gears: when 2 gear-pairs overlap (use the same nodes for their axes), it was unable to fixate relative angles of one of the gears.
- fixed: Tab-pages of many dialogs showed a grey background, which is not conform Windows 7 default settings.
- fixed: Starting SAM with invallid license data disabled the use of SAM in demo-mode.
- new: Reference to SAMxx.INI setupfile may be added to a commandline launch,.
- fixed: Deleting Elements could result in unreferenced "ghost" nodes.
- new: Hotkey added for Project Documentation: Ctrl + f
- new: License activation. Paste the complete activation key at once.
- fixed: Project Documentation: Hinge info was incomplete.
- fixed: Range-check error while creating project documentation.
- fixed: Format error in reference file for Optimization resulted in repeated error message. Process is stopped now and show a clear message.
- fixed: Using exact values as argument in an Optimization resulted in a range-check error
- fixed: The "Save" command acted as a "Save as" command
- fixed: Hidden feature added to hide the filename and path in the SAM titlebar. See SAM INI > [Global] > ShowPathInTitle
- First release of Sam 7.0

The number of support conditions, (relative) fixations and defined input motions of the mechanism must be such that the system is kinematically constrained. If there are not enough constraints, the mechanism is called "under-determined".
The number of support conditions, (relative) fixations and defined input motions of the mechanism must be such that the system is kinematically constrained. If there are too many constraints, the mechanism is called "over-determined".
In a kinetostatics analysis the input motion is pre-defined and the software calculates the forces that are required to perform the pre-defined motion. In a dynamics analysis (not supported by SAM) the driving forces are defined and the resulting motion is found via numerical integration.
In some cases one wants to analyze a mechanism with an inclined linear guiding, which can not be modeled by "fixing" a node because this approach only works for horizontal or vertical linear guiding.
However, an inclined linear support can be modeled on the basis of the slider element. By fixing both the node and the angle of the base point of the slider, the moving node can only slide along a fixed line.
In general an update (bugfixes, indicated by an increased build number) is free of charge (it can be downloaded from the website and used with the existing license key).
An upgrade offers new functionality (new functionality, leads to a new major/minor version number depending on the level of new functionality). An upgrade requires a new license key. This is offered to existing customers at reduced costs, which depend on the customer's current version. The upgrade costs are based on the cummulative upgrade steps (for example: the costs of upgrading from SAM 5.1 directly to SAM 6.1 are identical to the sum of upgrade steps SAM 5.1=>SAM6.0=>SAM6.1).
When upgrading the license count, or the license level of the same release, the difference in purchase price is charged.
Please see the detailed price list for the current upgrade prices.
