AutoFEM Analysis Assigning Initial Conditions | |
Besides specifying of the initial velocities and accelerations using special commands, user may also define initial conditions using the results of previously solved statics or dynamics studies. Important condition for such usage is the requirement of identity of the finite element meshes in both tasks. The parameters are set on the Parameters tab in the Initial conditions section. You can use one of the two ways:
•Apply displacements from the static analysis.
•Apply results of dynamic analysis.
In the last case you can apply not only displacements but also velocities and accelerations from another study to the initial step.
