Need Help concerning FEMAP Software

By Future Dynamics on 19 Apr 11:03 4 answers 2 comments

Hello everyone,

I have porous structure and I want to do FEA Analysis using FEMAP Software, but there are some fatal error are coming.

could someone available in grab cad community who is familiar with FEMAP Software. I would be very much thankful. looking forward to hear from someone soon.

    Can you describe your fatal errors? Are the errors software or geometry related? What is the approach, linear or nonlinear FEA? Is there a chance that the error occurs in your preprocessing (Meshing, Boundary, Constrains, Material)

    Hi Andrea’s,
    Thank you very much for the answer.
    Well as I said I have porous material structure in IGES Format which is openable in FEMAP 11.1.2 NX Nastran software without any problem.
    I need to create crushing model, therefore I introduced two steel plate one at bottom as a fixed plate while second one movable plate for the pressure exertion.
    When I try to make contact with the model and steel plate, there are some problem.
    Secondly when I do meshing of steel plate there is no problem, but when I do meshing of model, the pointer start synchronizing.
    During the analysis , I choose Linear analysis option.
    I am not sure what is going on as I am totally new to this software. I am using inbuilt aluminum 6061 property for the model, while for pressure plate I am using the same inbuilt 4131 grade steel property.
    So I am confused what to do and with whom shall I consult,

    I would be really thankful andreas please help me with this if you can.

    Maybe the steel plates might give the error. If they don't share topology with your model, you won't get a continuous mesh. So the solver is not able to calculate on the entire system. Why don't you just constrain the model without steel plates on the bottom of your model , like: ( y = fixed, x = free, z = free) and then apply the compression forces...If you use aluminium as material than the model won´t response brittle. The material can deform plastically. So I assume you want to analys the model according buckling behaviour? Unless it is a aluminium foam....than I would incorperate very thin aluminium sheets into the foam and make a model assembley, where you then constrain the sheets.

    please see in the attachment file error box arise during the meshing of model
