    Hello everyone:

    A problem puzzeled me recently.I'm a composite wind turbine blade engineer. The blade cross sections are conplex,as we can see from the attatchment figure.How calculate every cross scetion property? I have some thoughts about this problem:

    Extracting the cross section information(node coordinates,elment,material property and orientation,layup information)

    Converting the information above to information that VABS can tackle with

    Running VABS

    Extracting properties(mass property matrix, stiffness matrix,etc)


    It's right?

      The figure is not attached. Normally, you should be able to draw the cross-section using a CAD software, mesh it and extract the information needed for VABS. Currently Hypermesh, and CATIA has direct link to VABS.

      Can you try to use PreVABS https://cdmhub.org/resources/1597 ?It looks to me that PreVABS should be able to handle this cross-section.
