Read FEM mesh information from FreeFEM++ msh (3D) file [Experimental version]
- Purpose
- Read FEM mesh information from the file in FreeFEM++ msh (3D) format.
- Parameters
-
| [in] | Fname | Input file name. |
| [out] | N | Number of points. |
| [out] | X() | Array X(LX - 1) (LX >= N)
X coordinates of points. |
| [out] | Y() | Array Y(LY - 1) (LY >= N)
Y coordinates of points. |
| [out] | Z() | Array Z(LZ - 1) (LZ >= N)
Z coordinates of points. |
| [out] | Lp() | Array Lp(LLp - 1) (LLp >= N) Label of each node. |
| [out] | Ne | Number of elements. |
| [out] | Kc() | Array Kc(LKc1 - 1, LKc2 - 1) (LKc1 >= 5, LKc2 >= Ne)
Connection matrix: Kc(0, K-1) is the type of K-th element, Kc(1, K-1), ..., Kc(4, K-1) point to the nodes of K-th element.
The type of element value is as follows:
= 4: 4-node tetrahedron. |
| [out] | Le() | Array Le(LLe - 1) (LLe >= Ne)
Label numbers of the elements. |
| [out] | Nb | Number of elements defining boundaries. |
| [out] | Ks() | Array Ks(LKs1 - 1, LKs2 - 1) (LKs1 >= 4, LKs2 >= Nb)
Connection matrix for the boundary elements: Ks(0, K-1) is the type of K-th element, Ks(1, K-1), ..., Ks(3, K-1) point to the nodes of K-th element.
The type of element value is as follows:
= 2: 3-node triangle. |
| [out] | Lb() | Array Lb(LLb - 1) (LLb >= Nb)
Label numbers of the boundary sides. |
| [out] | Info | Return code.
= 0: Normal return.
= i < 0: The (-i)-th argument is invalid or has an illegal value.
= 11: File open error.
= 13: Data format error.
= 16: Unexpected end of file. |
