Hello IRStuff, Matrix*vector is only 1 - element vector (not a matrix)

Hello all, I am new to mathcad, I have a matrix (ixj) and a vector (ix1). I need to multiply each ith row of the matrix and the vector. Eg. My first row is (2,6,1) and second row is (1,2,3) and vector is 2,1,3. My resultant matrix first row should be 4,6,3 and second row should be (2,2,9)...and...

hello guys. I use Femap, server based NX nastran and visQ. I know there is a option to PROMPT the file name for the .dat file (Nastran input file)when you click analyze button. I dont want to use auto generated file name Modelname000.dat for Nastran input file. Can anyone help me to locate...

Go to model info - left click on analysis - manage - (in analysis set manager) - click edit - next - next - in FORMAT option set radio button to LARGE FIELD. This should work San

They said they have internal program bug that stops nastran on 1st april 2009. They are fixing it. (1 april 2009, 2:45 CT) here is the email from them! [ Siemens PLM Software ] S O F T W A R E SFB-NX_Nastran-4514 F I E L D...

Thanks Andrea.. I guess the size of the mesh controls the nodal and elemental stress values.. If we have fine mesh these values should be same.

Hello all, I am a beginner here. Femap offers many types of output option for post processing.. They have elemental contour, nodal contour, with min max and average options.. also the element contours with corner data, or element contour without averaging..etc etc etc... Among all these...

Thanks for your reply rb1957 "all FEA programs will want to mesh a 3D solid with 3D elements. if you Really want to use 2D, most likely you'll have to mesh one surface (inner or outer) of the part." This is what I am going to do.! Thanks

Its a ProE assembly (Bunch of parts) I do not want to use ProMechanica nor ProFEM. I dont think one "mechanica button" is good enough to run the analysis. I do not have anything but assembly made for manufacturing drawings in ProE. I want to convert this model in to Femap. I can not directly...

Thanks for you help rb1957, What do you mean by iges, Neutral? Should I save ProE assembly in this format or what? what next? Yes I can run this analysis in ProE using Promechanica.. But client want to use femap...

I have a large welded structure (I beam, L beam)in Pro E assembly. I want to make this structure in Femap to run analysis. Right now guess I need to measure all lengths and intersections and make nodes in Femap to generate elements. Is there anyway I can add points, datum points or lines in Pro...
