Prestep Response of ElasticIsotropic vs MaxwelIsotropic Rheologies

Hi Brad,

I am getting different Elastic Pre-step deformation by applying ElasticIsotropic3D and MaxwellIsotropic3D (linear Maxwell Viscoelastic) for my model (fig below).


In my understanding the linear Maxwell model (which is a spring and a dashpot in series) should give same elastic prestep response to that of an elastic model, given that we have identical elastic properties for both the runs.
I have checked the input scripts and they all seem fine, is there an explanation to this or I am doing something wrong?

Thank you
Viven

Hi Viven,

Could you provide the input files that you are using for the two cases?

Thanks,
Charles

Hi Charles, thanks for the reply.

As it turns out that there was some error (from my side) with the input files. The pre-step results are coming out to be same now.

Thank again
Viven

OK, that’s good to know.

Thanks,
Charles
