Hi STKO,
How can I extract internal force in the basement wall?
I can not find any "force result" on nodes, on element gauss points, on element sub-gauss points (fibers) in post-processor. But I can see some "force result" in surface color map.
Please refer to my model in attachment.
Thank you,
Buu

The results on element nodes (such as force) cannot be extracted using the "Extract Chart Data" command.

If those nodes are also the fixed ones, you can simply extract reactions at those nodes and change the sign.

Otherwise, it can be done using the PythonAPI script. If you need it and you don't know how to do it we can do it here

Thank STKO team, I successfully extracted.
I have one more question, is there any stress in zerolengthContactASDimplex that I can extract from its recorder?
Im trying to get the earth pressure on the basement walls due to adjacent soil.
If I extract material.stress from adjacent soil (sigma22) as earth pressure, it seemed not correct compared to experimental result. Thats why I want to compare the earth pressures extracted from soil's material.stress and those extracted from zerolengthContactASDimplex element.
Thank for your help,
Buu

You can ask for localForce.
It will give you 3 components. The first one (N) is the normal contact force. This is the one that you want.

However, it is a force, not a stress.
If you want to obtain the stress from it, you can divide it by the tributary area of the contact node:

you mean localforce in element result, right? as showed in Figure 1.
When I showed the results as in Figure 2, the local forces are in the beam elements (walls), not existed in soil element.
But I think N component in local force of beam element is not what I want.
Can you check my model in attachment?
Thank you!
Buu

localForce is a result common to many elements. You have to pick the right one for the ASDimplex contact element.
Since it is a zero-Length, it's useless to view it in SurfacePlots. Instead, you can look at it in gauss plots:

Yes, The points are so small, now I can see it if zoom in
Thank you for you help,

Change the particle size scale factor as in the previous image
