LISA - Free / Affordable Finite Element Analysis Software

Active-X Port

ActiveX Sample

LISA-ActiveX was used in :

LISA' ActiveX Port enables Software developers to write their own programs which can call on the LISA engine to accomplish the more difficult tasks of mesh generation and equation solving or for routines like stress classification, FEA results documentation, etc. Using ActiveX, the LISA Pre- and Post-processor can be integrated into a Software Application. This use of LISA is similar to a Dynamic Link Library, but here, LISA is called the ActiveX Server while the Software Application is called the ActiveX client.

Another way LISA deals with ActiveX is with the LISA OLE container and the LISA Add-In Manager. In this case LISA will be the ActiveX Client and your Application which will be added as an Item to the LISA Add-In Menu will be the ActiveX Server.

To write ActiveX clients/servers for LISA you can use Microsoft Office, Microsoft Excel, Microsoft Visual Basic or any other programming language which supports Microsoft Active-X Programming.

create re-sizable FE-Models (same shapes, but varying dimensions) so that only variable values of the mesh dimensions have to be entered to generate the mesh. This will find application in the analysis of a family of similarly shaped parts but of varying dimensions

automate stress classification and documentation of FE results. If you use resizable FE models you may also want to automate the Stress Classification in the documentation of the FE results.

The multi-physics features of LISA can only be used via ActiveX. An ActiveX client helps you to control the LISA solution procedure for a multi-physics analysis such as fluid structure interaction, temperature distribution and thermal induced stresses, simple non-linear analyses, modelling of phase change problems etc.

Job scheduling: Solving a number of models over-night by controlling the LISA Solver from another Application

Contact Analysis: The first solution must check the contact elements, modify their elastic modulus and then perform a second solution. Again, the contact elements must be checked and their elastic modulus modified, so on and so forth.

have programs compute, for example moments of inertias or additional property values

add mesh generators to LISA

add databases to LISA

develop file conversion utilities
