Simcenter Femap APIs - Automation Programs

The nodes in a model are moved to the deformed locations of a selected output set by this API.

Often it is desirable to import point locations from a saved text file into an open FEMAP session. The API will import point locations in the x-y plane.

This is a very handy API program to have. When setting up a complex model that contains many rigid links, it is important to ensure that a slave node is subject to only one master node. This API goes through all the rigid links in the model, and lists any nodes associated with more than one rigid link.

The focus of this program is getting a Quad Surface Mesh just right. It allows for the specification of selected mesh properties, and the capability to remesh quickly.

Frequently complex connections between components can be idealized with the creative use of rigid body elements (RBEs). An analyst can "zip" together different components using node-to-node RBEs where each element only has one dependent node and one independent node. In the case of non-zero length RBEs, a different selection of dependent and independent nodes will result in different results.

Manually "flipping" these elements (swapping the independent and dependent nodes) is a time consuming and error prone task. This API will automate the process and make element selection easier for the user by automatically excluding non-RBEs, RBE2s with multiple dependent nodes and RBE3s with multiple independent nodes.

Random Vibration Analysis

UPDATED!

The API will take PSD RMS displacement and stress components (the X, Y, XY components) from plates and solids (X, Y, Z, etc.) and calculate a conservative PSD RMS total translation and von Mises stress components.

After the API finishes, you can contour top and bottom plate stresses and also view the total translation. It is super useful!

The Non Structural Mass Manager macro allows the user to quickly add non-structural mass to specific properties in a model from an Excel spreadsheet.

Revolve Multi Surfaces allows the user to select multiple surfaces and revolve them around the same axis.

These APIs generate new output vectors that summarize stress results across all plies within a layup. Additional output vectors let the user know in which ply and output set that the maximum values are found.

The Select Independent Nodes macro enables the user to select a rigid body element (RBE) and the API will select the independent node(s). The independent nodes can then be highlighted using the highlight tool in the model tree.
