Re: K matrix
Hi Erik,but do you know the file where I can find the Matrix? And how can I open it? In truth I would the eigenvalues. Is there another method for get them?

Giulio I do not know where and in what format the Matrix is stored, eigenvalues (and eigenvectors) is easy, run a modal analysis. Erik

Hello All, Why do I have so many qualityagent.exe's running? It may be related to global sensitivity studies. I periodically end the processes because they eat all my cpu. Any thoughts? Creo3.0 M030...

I've read that a way to determine if the "numerical quality" of the mesh, is calculating the conditioning number expressed as the ration between the max and min of the eigenvalues.More this ratio is...

Giulio You're not wrong, but a) you can come close to K eigenvalues if you choose M small --> use a very low specific mass.2) if you go for normal modes (even with correct mass) and you look at...

Hi Erik,I guess your tip of using a very low density to bring closer the matrix K to the matrix "A" is the better way to get a numeric validation.

Hi! I´m running a model with contacts so the analysis must be non-lineal for best results. Then I must analyze the fatigue but CREO say I must select a previous lineal static analysis to do. So if I...

Large deformation+contact + preload (modeled using solid elements only - not beams or fasteners unfortunately) is OK. But as you say, this cannot be combined with fatigue, which requires a linear...

Re: Fatigue and non-lineal analysis
If you're running a mult-body contact analysis in Creo, and if you're trying to run Fatigue Advisor in Creo, then this will not work. Fatigue Advisor can only be used on a single component.

Hi Steven and Don, So this is a great lack of CREO, because there are so many nonlineal Systems independently of the characteristics of the materials, so many Systems with contacts for example. And...
