Create an FE Mesh of solid tetrahedral elements from a domain defined by a closed surface mesh. This function will remesh the input domain to generate FEA quality elements.

### Inputs

| Name | Type | Description |
| - | - | - |
| Domain | [Mesh](../../../../block-documentation/types/mesh) | The input domain defined by a watertight surface mesh. The input surface mesh will be remeshed to obtain FEA quality elements. |
| Edge length | [Scalar Field](../../../../block-documentation/types/scalar-field) | The target edge length of the elements. Note that the input can be a scalar field to achieve a spatially varying mesh size. |
| Geometric order | Geometric Order Enum | The geometric order of the output mesh. The linear option may be suitable for a fast analysis, but quadratic elements are recommend when accuracy is more important. For quadratic elements, the mid-side nodes are inserted along the straight edges of the elements. That is, the quadratic elements are not curved. |
| Span angle | [Scalar](../../../../block-documentation/types/scalar) | The maximum spanning angle for elements on a curved surface. The smaller this angle the more elements will be generated to conform to a curved input. |
| Growth rate | [Scalar](../../../../block-documentation/types/scalar) | The rate at which the size of adjacent elements can grow. |
| Feature angle | [Scalar](../../../../block-documentation/types/scalar) | The angle used to automatically detect feature angles in the input domain that will be preserved in the output mesh. |

### Outputs
