Linear elasticity- boundary conditions

[Therookie]

Hai,

I was trying to run a simple linear elastic problem of Disk under diamteral compression. The disk is model in GMSH with radius 20 with bottom node (0,-20) fully fixed (x and y) and top (node 0,19) x fixed with displacement allowed in -y.

The code is running but not output neither the stress fields and u as exported to para view. Attached Snip of the BCs

If i want to apply a point load at the top how should i modify?

Please also note that it is adviced to supply a minimal code example, encapsulated with 3x`. For more info on minimal examples, see:

Here are a few tips to help get your question answered: Phrase the title of your post as a question and make it meaningful. Check that your question hasn’t been asked before using the search functionality. Post a “minimum working code example” (MWE) to illustrate the problem: A MWE is the simplest piece of code that reproduces or explains the problem you have. It must be possible to take the MWE, paste it into a file and run it, without any extra modifications. Good MWEs can be as little as …
