# FE Volume Mesh from Implicit

Create an FE Mesh of solid tetrahedral elements from an Implicit Body.

### Inputs

| Name            | Type                                                                 | Description                                                                                                                                                                                                                                                                                                            |
| --------------- | -------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Body            | [Implicit Body](../../../../block-documentation/types/implicit-body) | The Implicit Body to mesh.                                                                                                                                                                                                                                                                                             |
| Feature size    | [Scalar](../../../../block-documentation/types/scalar)               | The minimum feature size to preserve in the Implicit Body.                                                                                                                                                                                                                                                             |
| Edge length     | [Scalar](../../../../block-documentation/types/scalar)               | 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. |
