Visualize random fields

Visualize random fields

Visualize random fields

(OP)
Hi all,

I'm trying to visualize the material properties (such as Emodulus, thickness, plasticity parameters, ...) of a random field. I've assigned the (elsewhere) generated material properties to every element and written them into an input-file. So far no problems, the analysis runs. But I'm trying to visualize these variables as an output variable (comparable to e.g. stresses). Is this possible in a relatively easy way. So far I've been looking at writing a UMAT and extracting the properties from there into a Field, but I use more then one material in the same model (composite and isotropic). I've already found a way to do the thickness via the output STH so that's solved. But the others still remain a problem.

I hope you could  provide me with some hints/directions to look for.

RE: Visualize random fields

1) You can use UMAT and store them in state variables (STATEV). State variables are available for plotting as SDV. Perhaps you might not even need UMAT but only SDVINI which is called at the beginning of the analysis to initialize the state variables.
2)If the materials properties are only function of coordinates but otherwise known (not solution dependent) you can use the scripting interface to create new fields in the odb and plot them in the visualization module.
