The translator creates the FIDAP Neutral File version 7.0 and offers the possibility to also write the Fidap FDREAD File.
The translator writes the FIDAP Input File using an unstructured mesh and its boundary condition file. To create the FIDAP input file, "Select solver" → FIDAP in the "Output" menu. After clicking "Write input " you can specify the following options for the interface:
The interface generates the FIDAP Input File located in the project directory. Defining entity name and thin surface for FIDAP
Currently, only two types of tagging are commonly used for FIDAP, the entity name or element group name tagging and the "thin surface" tagging.
To define boundary condition click on the "BC" icon in the "Output" menu. Supported boundary conditions are:
|Entity name||enter a name, default is part name|
|Flux/Free boundary condition||degree of freedom flag
degree of freedom
|Boundary element group||degree of freedom flag|
|FIDAP boundary condition||label
|Nodal boundary condition||degree of freedom
Thin surfaces can only be defined on interfaces between two blocks and therefore exist only in 3D models. When such an interface is defined "thin", all the nodes interior to this surface are duplicated but NOT the nodes on its edges. As a result of the duplication, two different element groups are created for the face, one with the original nodes, the other with the "twin" nodes. Aside from the edge nodes, the 3D element groups on each side of the face also use different sets of nodes.
If two or more interfaces tagged "thin" meet at a common edge, the user may want this edge to be regarded as "interior" and therefore have its nodes also duplicated. For this purpose, edges can also be tagged "thin".
To define a thin wall (and thin edge) set the 'Entity name' of the part to the word "THIN".
