User defined results in APDL

[miroslav1312]

hi every body

I would like to plot contour of some expresion in ANSYS APDL
the equation is sigma:epsilon+const sigmma-tensor,epsilon tensor
Is it possible in ansys APDL to do it as a user defined results
if yes please how?

Thanku very much

I don't understand your equation, but you can retrieve all the elements from the stress and strain tensors with *VGET in the form of vectors.
Then you can operate with those vectors with *VOPER
And finally you can insert the result from the solution vector into the database with *VPUT (you have to overwrite a result you are not using with your custom result and then plot it with PLNSOL)
Look up these commands in the ansys help.

You may look into ETABLEs for plotting custom contours. You can operate on ETABLEs with SADD and SMULT. PLETAB will create a contour plot of your ETABLE.
