Dear STKO team,

I have been trying to run a model of a reinforced masonry wall, but it gives me the following error message when trying to run the model: "writeTcl() missing 1 required positional argument: 'xobj'. I need your help to solve this problem.

kind regards,
Benjamín

There are some errors in your model:
Try to fix these 2:

• Your geometry has some faces that cannot be meshed with structured quad mesh (they have more than 4 edges). If you want to keep it as it is, switch to unstructured triangular mesh, and choose a triangular shell element. Otherwise, cut your geometry to make it suitable for structured quad mesh:

• You are using a uniaxial section for an elastic timoshenko beam: it's not correct. You should either use an elastic section with an elastic beam, or a nonlinear section (for example fibers) with a nonlinear beam column

Fix those first, and let's see if there are other mistakes

Hi STKO team,
I fixed the geometry problem and the problem with the top and bottom faces using a elastic membrane section in shell elements, but now apparently the problem is something else.

sorry, i forgot the picture and the model but here is.

Hi, Your model works fine on my end. I use recent version of STKO v4.0 released yesterday. Please check the attached file. Use parallel version of OpenSees
