In time-dependent simulations, you can use automatic remeshing instead of the stop condition. The software then creates new meshes when the mesh quality drops below the specified level. To do so, click the Step 1: Time Dependent node () and then select the Automatic remeshing check box in the Settings window’s Study Extensions section. To use the same condition as for the stop condition above, select Distortion under Condition type, enter comp1.ale.I1isoMax in the Distortion expression field, and enter 4 in the Stop when distortion exceeds field in the Settings window for the Automatic Remeshing () node (under the Time-Dependent Solver node in the solver sequence).

In the Settings window for the study step (for example, Study 1>Step1: Time Dependent), use the Mesh list under Mesh Selection to select the new meshing sequence (Mesh 2, for example).

Change the Times list under Study Settings or the Parameter value list under Study Extensions to include only the time or parameter corresponding to the deformed configuration plus the remaining times or parameters.

Change the initial value to be the last time or parameter of the previous solution. Do this by expanding the Values of Dependent Variables section in the study step settings. Under Initial values of variables solved For, change Settings to User controlled; then change Method to Solution, and locate the previously created solution copy. Then select the appropriate time or parameter value in the Time or Parameter value list. Usually the Automatic setting, which selects the last time or parameter value, suffices. Change the settings under Values of variables not solved for similarly.
