    FEMAP Model of Circuit Card Assy Help

    Blas: Do you need to model the chips as a separte "part" or can I simply extrude them out of the mid surface I created for the pcb? I have seen that you can assign different materials to the extruded chip.

    FEMAP Model of Circuit Card Assy Help

    Blas: I agree that the small chips will not stiffen the board. Just for fun let's say I have a larger chip like a BGA that may add some stiffness. The manufactures give dimensional data but not chip material info. I have an old Solidworks FEA training manual that used Ceramic Porcelain for chip...

    FEMAP Model of Circuit Card Assy Help

    Hello Blas: Thanks for all of the advise. I really like that you are giving specific FEMAP instructions not just general. Randy

    FEMAP Geometry Edit Questions

    Thanks folks. This all makes sense. I think I will make sure to import the geometry. It will save me a lot of time.

    FEMAP Geometry Edit Questions

    Blas: Thanks for the advise. FEMAP is nothing like the CAD packages I have used. It is a wonder they have not embraced a better parasolid module to make modeling easier and faster. I imagine it is all tied into the mesher. Randy

    Add Hole to Surface

    Can someone tell me how to turn the boundary surface I created in the lower left corner into a hole?

    FEMAP Geometry Edit Questions

    I have been posting in the FEA section by mistake. OK folks by now you have figured out that I a brand new to FEMAP. This software is making me feel like a total idiot. I have been thru all of the examples and I still can not get off of the ground. I am trying to build a very simple model, a...

    Thanks for all of the help.

    FEMAP Material Assignment in Assembly

    True I am a newbe to FEMAP. I worked thru most of the tutorials but only one delt with an assembly and they chose to assign the same material to all parts. I slugged thru the manuals and read between the lines and figured it out. FEMAP really needs more examples and/or pics in the Commands text...

    FEMAP Material Assignment in Assembly

    How do you assign different material properties in an assembly? Example, part 1 is 6061-T6 and part 2 is Alloy Steel. I tried using mesh/geometry/solid, pick the geometry and then Load the material and select the material. Nice and easy. I used the same approach to assign a different material...

    FEMAP Training Material

    I am new to FEMAP and have been looking for training material. I found the Examples, User's Guide and Commands and they are helpful. Has anyone found additional training material? I am still reading but so far I have not found how to handle mixed mesh modeling ie shell and solid elements. I...

    FEMAP Model of Circuit Card Assy Help

    Has anyone used FEMAP to analyze a circuit card assembly with its components? I am trying to determine the change in the natural frequency of a loaded PWB. PRO/E (boo hiss) will be used to generate the geometry. Once imported into FEMAP, I changed the PWB to a midsurface (ie shell elements)...

    FEMAP Model Regenerate

    I may have tripped across this process a few minutes ago. Thanks for posting.

    FEMAP Model Regenerate

    Since it was only a modal analysis with no loads, a constraint is not required. The only trick is to realize the first 6 modes are basically zero because they reflect the 6 degrees of freedom. Mode 7 is really the first mode or fundamental frequency of the unsupported model. I learned this trick...

    FEMAP Model Regenerate

    I worked thru almost all of the Examples and none of them discussed the problem I was having. Is there another set of tutorials available? I am willing to work thru anything to help get me up to speed. I tried to find a text book but it appears none have been written for beginners in FEMAP...

    FEMAP Model Regenerate

    A coworker just answered the question: The results are appended to the end of the previous set so if you are requesting 10 modes, the 2nd run should be modes 11-21. I looked and this is the case. FEMAP is nothing like Solidworks Simulation!

    FEMAP Model Regenerate

    I just found the rebuild icon and it did not help. Again, there must be a way to iterate a model without starting over for a simple constraint change.

    FEMAP Model Regenerate

    I am new to FEMAP. I have what I hope is a simple FEMAP question. Say I have a square plate with all four edges constrained. I run a modal analysis and get an answer. For kicks, I deleted the contraints and used model/analysis/analyze to re-run the model. It runs but the results are the same...

    How to add mass to Pro/Mechanica Model

    I guess it really does not take any time but I hate "faking" the model to perform this task. If someone else was to use the model,the change in density or reason behind it would not be obvious. This just seems like a dumb way to solve the problem. Of course I am new to the software and I resist...
