Got no stress results from coupled thermal stress analysis

Got no stress results from coupled thermal stress analysis

Hi All

while simulating a coupled thermal stress analysis, I noticed that I only get the NT11 results, and no stress

it's an RC beam, the elements are chosen accordingly : coupled temp disp

I have applied one step as initial temp applied to parts :25° as predefined field in all part

then second step, a TEMP BC to a surface of concrete

but I don't get any stress results. I have defined thermal, plastic, elastic and damage parameters for concrete and steels ..

RE: Got no stress results from coupled thermal stress analysis

It there an expansion coefficient in the materials?

RE: Got no stress results from coupled thermal stress analysis

Thank you for your answer, no there wasn't, I have added it, but the analysis doesn't converge

I am using mmKgs system, for steel and concrete I have entered 12 and 9.8 as expansion coefficient, then after not converging, I reduced them to smaller numbers assuming I have assumed a wrong unit. but still the same problem

RE: Got no stress results from coupled thermal stress analysis

Check you general method and input on a simple example first (a block, e.g.), where you can see directly if the results are correct.
