NLGEOM analysis problem

Recommended Posts

Dear all

      I am using NLGEOM method to solve a nonlinear problem. I want to use discrete date to define material. And the first (x1,y1) are (0, 310), 310 is the initial yield point.

But when I analysis, there comes a problem. The following shows the problem.

 *** ERROR # 3002 ***
  The first point (X1,Y1) specified on the TABLES1 bulk data entry ID=5
  is not located at the origin of the stress-strain curve.

 

I don't know why, could you help me with that?  The model I used is as follows.  Thanks!

The LIMIT1 field can be blank, if the initial yield point value is defined via a referenced TABLES1 entry on the TID field.

I tried that, but it doesn't work.

Error 3002.JPG

hi, Rahul

     I have already set TYPSTRN value to 1, but there still comes the error message. I don't know why. Eager for your answering. Thanks!

 I checked your model & it seems that you defined MATS1 parameter correctly.

I ran your model and it ran complete without any error in 14.0 (210 solvers patch)version.Same file if i run in 13.0 it throws error 3002.I am not sure about reason.

But if you have access to 14.0 please try same in latest version.

Thanks for your patience. Sorry I don't have access to 14.0.  

I have changed the first date to (0,0), second data to (0,310)  and set TYPSTAN to 0, then it can be run without error.

But I don't know whether the result is right or not. Could you tell me?

Most of the time we accept results comes out of implicit solver.I believe you would have setup load & boundary condition property with correct material properties.

If testing results is available then one crosscheck with same.Results is right or wrong that analyst need to evaluate based on engineering skills.
