Re: Help to apply shear force at boundary

Hello Thomas, I have run into some more issues with this ice block case. To answer your previous question, in our lab experiment the top and bottom faces can be held in place so they don’t move vertically. I am having some trouble introducing the horizontal motion though. I have implemented free sur...

Re: Navier-Stokes solver convergence issues

Hi Peter
Thank you very much for telling me this. It is good to know that the issue was things that were missing, not things that were incorrect per se. I will continue working on it.

Re: Navier-Stokes solver convergence issues

Since the last post I have made the boundary conditions and the mesh geometry more realistic and I understand a lot more about what the boundary conditions do now. However, I still can't seem to get the Navier-Stokes solver to do a diagnostic run. Using the ElasticSolver and equivalent BCs works jus...

Navier-Stokes solver convergence issues

Hello, I am having some problems with the Navier-Stokes solver. I would like to perform a simple diagnostic test to apply pressure to the top of a cube of ice and get the stresses as an output. I have modified the ForceToStress test case to create a simple example. However, if I replace the ForceToS...

Re: Help to apply shear force at boundary

Hello Thomas, Thank you for your detailed help, I really appreciate it. With what you have told me I can move forward now. To answer your first question, I realise that this test case is unrealistic. At the moment I am just aiming to create a block and put some forces on it as a step towards a more ...

Help to apply shear force at boundary

Hello, I am working on modelling a very small rectangular prism of ice. Imagine a block of ice with larger sheets of some other material firmly attached to the top and bottom. If you pull on the top and bottom in opposite directions the result will be a shear force experienced by the ice block. Shea...
