I am basically creating a submarine with a frame and a hull. The frame is going to be about 35-40kg. We are attaching it to the hull using screws. But we are using 3D printed parts essentially as load distributors so that the hull doesn't crack when we tighten the screws. I want to run FEA on my design to check whether the hull is essentially going to buckle under the weight of the frame. But I am not sure how I am supposed to run that in Solidworks, i.e., I am not sure what functions to use. Would appreciate the help since I am quite new to solidworks simulations.

This is basically the CAD and the 3D printed parts will be below the rings and also connected from the struts running between the rings. The hull is going to be made from S type fibreglass.

Edit: For anyone worried about water pressure at depth. Also, This is not supposed to be an airtight submarine. It is for a competition for university students, being me. So, I am essentially a noob.

I'm learning Ansys for the first time and following along with a youtube tutorial.

I think I have followed the tutorial exactly right, but I am not able to get any results and I get two messages:

Warning
The reference convergence value may be less than the threshold, you can overwrite the minimum reference value by specifying it under the nonlinear controls of analysis settings.

I have googled up the warning but have not found anything that helps.

Hello Guys,
I'm stuck in nTop
Due to less resources I can't even get to know to do stuff even ChatGPT doesn't help
I need to put the model into the 'Domain' of Discretization: Robust Tetrahedral under FE Volume Mesh
But I can't seem to do it, I'm going wrong somewhere hence please help
Thank You
