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.

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...

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

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

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

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

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...

LPSs???

Thanks for all of the help.

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...

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...

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...

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)...

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

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...
