Problem with Large displacements simulation
Hello!!
I am triying to simulate a wing model with the large displacements card activated.
The model worked well with the loadstep type "Generic".
To make this simulation, first I switched to "Non-linear Quasi-static" analysis type.
Then I created a NLPARM load collector and added it to the loadstep in NLPARM(LGDISP) option.
The problem is that when I start the simulation, the Nonl_EUI_st, Err_EPI_st and Meas_EWI_st values does not change so the simulation does not converge and I get the error #4965 --> Maximum number of time increment cutbacks reached.
I have tried to use the NLADAPT card, changing the NCUTS option, and changing the NINC and the MAXITER in the NLPARM load, and nothing works.
I have also tried to put the NLPARM card without large displacements and it went well, so the non-linear quasi-static option is okay, the problem is only with large displacements option.
I even made a simplier model and the simulation went well!! So I dont know what is the problem with this file.
Thank you for your help!!
