SOL 601 Setings problem

Hi,

 

Recently I began to study the contact nonlinear problems. I try to simulate the sliding bearing, the outer part is rotated by moving the node with the time law function. Below You can see the model, contact and solver settings:

When I try to Analyse, I have such messege:

In *.f06 file I find this message:

 

*** Reading Nastran data ...
 
       ***ERROR: Discontinuity is not allowed in TABLED2 1.
 *** FATAL ERROR: PROCESSING OF NASTRAN DATA FOR SOL 601 FAILED.
 *** ADVANCED NONLINEAR EXIT CODE 0 ***
 *** ISHELL PROGRAM 'NXNA' COMPLETED ***
 ^^^ USER FATAL MESSAGE  
 ^^^ ERROR IN ADVANCED NONLINEAR MODULE          0
 ^^^SOL601 FAILED  

 

I changed a lot of options, but did not get a positive result. Please explain me what I do wrong.

Hello!,

The problem seems to be related with the Time function you use to control the applied load, revise it, not repated points should exit.

Also, if you prescribe an enforced displacement using a non-cero value, remember that you need to constrain the same DOF as well, OK?.

Best regards,

Blas.

Blas, thank you for your help !!! In fact the problem was in the function, I realized that introduced twice the same value at one point of time. Once again thank you for the timely help!

 

Please tell more about youre second advice - DOF constraining. My model has such constraints:

Dear Igor,

In FEMAP take a look to HELP > EXAMPLES and run Example#31: SURFACE TO SURFACE CONTACT, you will realize that when you prescribe a non-zero enforced displacement of say TX=2.25inches using MODEL > LOAD > NODAL > DISPLACEMENT command then those nodes should be constrained as well using MODEL > CONSTRAINT > NODAL and selecting the TX DOF, OK?.

Best regards,
Blas.

Thank you Blas! Your advice are very helpful! Bearing is spinning now.
