I think that you need explicit solver and CCX is implicit and explicit solver. See *DYNAMIC input deck. In explicit analysis no iteration is required as the nodal accelerations are solved directly.

I attach file relative to static sensitivity analisys and mesh convergence. You will find 3 plates: first and second the real plate with different boundary. The third a plate with a/b = 3. This ratio, not very different from 2000/600 of the real pla…

Conceptually is not complicated but is a NAFEMS challenge. So is necessary to perform a FEA considering all the steps. For example: a) Boundary: perform linear static to know if boundary condition will affect the results. If boundary are iperstatic …

I don't know because you need to model a weld. Take into account that you coul find a severe stress concentration. For weld verification against fatigue load using FE model see IIW recommendations. There is specified how to model the welds using two…

P.S. I done it with mecway. If anyone needs LIML file I will post it

I knew....I'm not a programmer but could be interesting to continue that project. I found a lot of good ideas on Roshaz and a good algorithm for tetra free mesh, quad free mesh, fast way to apply loads (over line, line pressure, face pressure, cone/…

I think that your model for simply supported beam is not correct. In fact end faces must be free to rotate. So Y displacement must be fixed only for bottom nodes and not for all nodes lie on the face. Try to fix Y displacement only for bottom nodes …

If you release the X displacement of one end node, in a nonlinear static analysis , you will obtain the same results of static analysis. It's typical "large deflection" problem and so is correct to perform nonlinear analysis. In ccx input deck is su…

Ok! For plotting displacents and stress components in cylindrical coordinates I use CGX typing "trfm cyl z"
-
So if you calculate the stress from buckling analysis (add S to *Node File) for the first buckling mode (Bukling factor =0) you will find the same stress derived from static analysis.

In ""in a linear buckling analysis the initial stiffness matrix is augmented by the initial stress matrix corresponding to the load specified in the *BUCKLE step multiplied with a factor"" CCX Manual

LIML file corrected

There is a macro in Roshaz. This kind of distribution is better than cos distribution when pin has a diameter about 95% or more of lug hole diameter. For example is very good for rolling bearing seat. I use this distribution for shackle-lifting lug …

I don't know...sometimes I look at the website but all is still at 2011. I think that project is dead and so I decided to contribute to Mecway. I must say that after 7/8 hours in Mw I appreciate the simpicity and the quick learning curve. For the re…

Thanks for your answer. I looked at some video tutorial about Mecway on youtube and I saw how to manage the inp file direct from the pre-processor. Obviously is a good way but I'd like a pre-processor fully integrated with CCX...obviously is my desi…
