## About this Block

**What it does:** Converts a surface mesh into a solid mesh. It is the preferred method for simple geometry, as it is speedy but less tolerant of defects.

**Commons uses:**

* Converting simple geometry surface meshes into solid meshes.

**Tips:**

* Use the **Remesh Surface** block to clean up the mesh before using the **Volume Mesh** block. When doing this, use the same Edge length in both blocks to easily create the 3D elements.
* You can vary the Edge length by using a Scalar Field input.
* If you get an error while using **Volume Mesh**, you may want to use the **Robust Tetrahedral Mesh** instead.
* The Growth rate specifies the ratio of element size from one element to another. The number can be anything greater than 1. The smaller the number is, the more uniform the mesh is.

Mesh a solid domain with tetrahedral elements that conform to the boundary of the specified Domain. If the Domain contains quad faces, quadrilateral pyramids will be used. The Remesh Surface block can be used to remesh the boundary Domain if necessary. If the input domain contains defects that cause this block to fail, consider using the Robust Tetrahedral Mesh block.
