Hi, I'm trying to extract the stress as the stress points using python code. If I extract the stress at the nodes, I get values out, but if I used 'stress point' I get just zeros. sigma_n = g_o.getresults(g_o.Step_85, g_o.ResultTypes.Interface.InterfaceEffectiveNormalStress, 'stress point')sigma_n = g_o.getresults(g_o.Step_85, g_o.ResultTypes.Interface.InterfaceEffectiveNormalStress, 'node')I can't find anything wrong with what I've coded, but was wondering if there was some box or something in PLAXIS I needed to tick to save the stresses at the integration points so that I can extract them. Does anyone know how to fix this?
Thanks, this is very helpful.
Is there a way to get the stress points. I want to calculate the force from the soil on the wall interface in each element from these points after that.
Do I need to get the stress points of the elements next to the wall interface?
Hello again,
Currently, it is not possible. Can you please elaborate on why the nodal results are not enough for you?
But indeed, if you are interested in results on stress points you can extract the stresses from the adjacent soil/rock element using the ResultTypes.Soil group.
To find the force per elements form the node values, I'd have to take an average of those and multiple by the distance between. With the stress points, I can use the weightings in the integration and get a more accurate answer.
I will try getting the stresses in the adjacent soil elements, thank you
Hey, I also want to calculate the lateral stress of soil from stress points. Can you explain how to do the integration?
