Hi everyone! I have a problem with the mesh generation. Below there is attached a picture and as you can see, there is an area with mesh in between 2 blocks. I tried everything like merge vertices, check and delete the elements which are over there, but in the pre-processing it appears as a default boundary condition and it gives me an error when I want to run the simulation. I am wondering if there is any way to solve this to avoid making again the blocks from the entire domain. Thanks!

When you say there is mesh between two blocks means you have already converted it to unstructured mesh?

Can you please explain full procedure.

I discovered the problem. But ansys is very strange. For example, if you pre-mesh and then suddenly you want to split a block and create a point or a line in order to assign the edge or vertex, then in pre-solver will show you as an extra boundary condition and you cannot remove it.

Can you please try 'Recompute' on premesh?

Can you please try Blocking - PreMesh Param - Update All?

Also as it is solved, can you please mark it as Is Solution to help others on forum.

Hi

I want to ask a question on student forum but i am unable to ask it. My question is below.

i am new to icemcfd. i am getting this error volume elements  were found for Uncovered faces. I will try to explain my procedure. please help me out.

-I imported my geometry and named the surfaces like inlet, outlet

- i created a block and further split it.

- on some blocks i required a coarse mesh so made them free blocks and did mesh refinemnt 1/3.

-i did pre mesh and the convert it to uns.mesh

- i have some hangiong nodes in order to fix it i did merge node then resolve refinement.

- when i go to check mesh i got this error
