Hello, 

You can upload your model to OneDrive or Google drive or any such similar location and share the url on the post (third icon from left). Due to sompany policies, Ansys employees are not allowed to download anything, but other forum members might be able to help you.

In the Solver Output file, I see that there are 4 elements that got turned inside out. I am not an expert in poroelasticity and coupled simulations, but hyperelastic materials also face excessive element distortion error sometimes and this error seems similar to that. Here's a video that may have some helpful tips that you could apply to your problem as well (the tips start at 10:05): How to Handle Element Distortion Errors in Hyperelastic Materials — Lesson 3 - ANSYS Innovation Courses

Hope this helps.
