Hide failed elements from result? [SOLVED]
I am doing a drop test (see attached video) with the ground modeled as a block of 4 node tetra elements and my object is also tetra. I am using LAW2 for both.
From the result I see that a chunk of my ground elements are reaching EPS_MAX and then they show 0 stress after that. I am assuming that they are 'dead' elements. They are still shown in HyperView as if they are still active (nodal displacements are still present). So how do I hide these elements automatically? If there is a better solution than hiding I am all ears. Basically I want to get rid of elements that have reached their ultimate failure strain.

Hello,
do you have tried to switch off the display of eroded elements by the following option:
Preferences->Options->Visualization-> switch of 'Display eroded elements'
Best regards,
Mario

Hi Mario,
It is already checked off on my PC.

Hello,
then the elements are not eroded and active. Looks like something is unstable at the simulation.
You can try to mask elements by contour (e.g. strains), but it is applied at the whole simulation.
Best regards,

Bongirs,
Deleting the elements using the EPS_MAX will not work for Mat Law 2 when you are using solid elements and only the deviatoric part of the stress tensor is set to zero.
You can try with ISO panel in HyperView. Use the Current value option
Set Above/Below parameters.
Above: Updates the graphics display so that all elements with result values above the current iso surface level are displayed (unmasked) based on their display attributes defined on the Entity Attributes panel.
Below: Updates the graphics display so that all elements with result values below the current iso surface level are displayed (unmasked) based on their display attributes defined on the Entity Attributes panel.
Please try this.

This is superb! I was looking for something like this for months. Thanks George!
