Geometrical non-linear implicit analysis

Punith

Hello everyone,

I tried a tutorial model for Geometrical nonlinear implicit analysis in Optistruct and I got this error. Can some one help me out what exactly is this error about?. I willl also attach my solver file here.

 

 * See next message about line 45 from file:
     D:/HYPERWORKS/HYPERWORKS_TEST/FORD_PressFitSimulation/NonlinearImplicit/plate.fem
  'GRID           3        0.0     0.0     0.0'
  
 *** ERROR # 1020 *** in the input data:
 Missing BEGIN BULK or line before BEGIN BULK has trailing comma.

 

Thanks and regards,

Punith Guptha

Hi 

try opening the file by notepad then add a line with 'BEGIN BULK' before above GRIG line

Hello

I ran your plate.fem file in Radioss17.2; it gives the attached error. Could you please let me know how to manage it?

Furthermore, do you know any tutorial for implicit dynamics, please? How can plate.fem be changed to have an implicit dynamic plate tutorial?

Thank you.

Hi @Question

 

You are trying to run an OptiStruct file using RADIOSS solver

 

Please use OptiStruct instead of RADIOSS.

Hi

Thank you for your help. I ran it in OptiStruct. It works well.

Do you know an implicit dynamic example, please?

Hi

Is it possible to have a time dependent load on plate.fem file and run it in implicit, please?

Thank you.

Please run a transient non linear analysis. 

 

Search for the same in the forum for a sample file
