Transient pre-stressed analysis
Hello to everyone,
I am working with a shock-impulse simulation. I'd like to do a Transient simulation. My model has pre-compressed sponges, this means that I must resolve a frictional contact in order to have the sponges in compression state. I thought that It was possible to do a Static Strcutural Analisys and link the solution with the Setup of Transient block (It is not possible).
I thought to do the same simulation of static structural analysis inside the Transient block in this way:
1) First step - No integration time and simulation for solving the frictional contact with penetration between Sponges and Top cover (With the same setup of Static Structural Analysis).
2) Second Step - Application of Shock impulse and activation of the time integration .
I state that the simulation inside the Static Strcutural block works and no problem of convergence occurs.
Inside the Transient block, during the first step the simulation does not converge but I can't understand which is the reason, becasue the conditions are the same of the Static Strcutural simulation. Maybe the solver of Transient block is not the same of Static Structural one?
