Hi guys,
after working with sHM for a while and didn't get the results that I needed I have to ask you some questions, to get a better basic understanding. The case I'm working on is comparatively simple. To simulate the flow of water around a floating structure and get the resulting wave pattern I want to use interFoam. The geometry of the solid that shall be examined I have as an .stl file and stored in a trisurface folder. And finally the background mesh is created with blockMesh (simple box with elements of an aspect ratio close to one). Everything is done according to the guidelines of of.com So now it comes to the snappyHexMeshDict file where I don't get every parameter, even after reading the manual more than twice. The questions that arose: Which is the parameter that defines the location of the stl geometry in the background mesh? I know there is a parameter called location in mesh, but what exactly is his function and where is the point he is located in the stl file (if this is the right parameter for that issue) How do I have to understand the splitting parameter? There is a level specification, but can I assume that level 1 splits one element in 8 sub elements level 2 in 64 and so on? What has the parameter locationInMesh with the cell removal to do? I hope these questions are not too basic thanks for your trouble Colin Edit: I got the snappyHexMesh comand running without any errors but viewing the mesh with paraFoam I couldn't find my floating structure within that mesh.
