Support โStatic Analysisโ
โข MBD for ANSYS now supports Static Analysis as well as Dynamic Analysis.
โข Using Static Analysis, users can find the static equilibrium of the system quickly and evaluate
the stability of the system. Various outputs (such as the reaction force) in static equilibrium
can be obtained.
Dynamic Static
Dynamic behavior over time Static equilibrium of the system

Support โinclude Staticโ in Dynamic Analysis
โข MBD for ANSYS will now provide an option to find the โstatic equilibriumโ before running
Dynamic Analysis.
โข Solver finds the static equilibrium first and then runs Dynamic analysis using it as the initial
condition. Since the initial condition in the static equilibrium can be calculated quickly, doing
this can save simulation time and make the simulation more stable.

Improved accuracy and speed of the solver
โข Various improvements have been made to the solver. These improvements will increase computation
speed and improve the stability of the solution.
โข The accuracy and the speed of the solver are improved by optimization of the algorithm.
โข Various general stability improvements in the time integrator.
โข Reduced effect of numerical damping.
โข Improved accuracy for high-speed rotation problems.
โข Improved accuracy for rotation of the bushing force
2x improvement

Simulink interface
โข MBD for ANSYS now supports the co-simulation with Matlab/Simulink. (Additional license is required)
โข The mechanical model of MBD for ANSYS and the control model of Matlab Simulink can be simulated
together. For example, the PID controller of Simulink model can be verified by co-simulation with the
mechanical model of MBD for ANSYS.

Stop condition
โข If the โstop conditionโ is met, the simulation stops even if the end time has not been reached.
โข The stop condition is met if the condition returns TRUE โ TRUE means a positive value.
โข This option is useful if the user wants to run a simulation until some specific condition is met and
doesnโt know when it is met. Since the simulation will stop as soon as the condition is met, it can
save unnecessary simulation time.

New syntax of the function expression
โข Conditional statement can be easily defined using signs of inequality. (for example, โtime > 3โ)
โข This is especially useful for expressions used to define the โStop Conditionโ.
eg1) time > 3
- If the time is bigger than 3, the return value is 1
- or the return value is 0
eg2) DM(body1.marker1, body2.marker1) < 10
- If the distance between two markers is smaller than 10, the return value is 1
- or the return value is 0
eg3) AZ(body1.marker1, body2.marker1) > 30D (30degree)
- If the angle about Z between two markers bigger than 30 degrees, the return value is 1
- or the return value is 0

Support the coordinate system to define the orientation of force
โข Coordinate systems can be used to define the reference marker of a translational force / rotational
force or the orientation of a bushing force.
โข Users can define the direction of a force more easily using this feature.

Display the base marker of joint
โข The base marker of a joint can be displayed. (by selecting it on the Outline window (database))
โข Users can easily recognize the direction of the x/y/z axis of the reference frame used to calculate the
output results in the ANSYS environment when reviewing the results in Viewer.
โข Up until now, users could only check the reference frame in Viewer.
Red: X axis
Green: Y axis
Blue: Z axis
