Hi, How properly constrain model including PRETS179 element to be converged? I`m trying to avoid this message... Preconditioned conjugate gradient solver error level 1. Possibly, the model is unconstrained or additional iterations may be needed. Try running with a multiplier MULT > 1 in...

Hi, How the best simulate clamp force (the preload) in 2D axisymmetrical bolted joint model??? I enclose link with screen to better understanding the problem. Thanks

I’m trying to find force magnitude needed to buckle mug. To do this I put pressure on the top and adding yoghourt inside I want compare behavior and buckling occurrence with and without yoghourt. Thanks your answer I have an idea to put pressure on the internal side of mug which will simulate...

The point of this analysis is buckling, I did eigenvalue analysis and non-linear analysis for mug and now I want complicate it by filling this mug by low density substance.

Hi, I created model of plastic yoghourt mug to my non-linear analysis in Ansys and in following calculations I want to add the internal part (yoghourt) to compare the behavior, displacements etc. What is the simplest way to modelize it? I should create solid inside and use contact elements?? Or...

HI I’m trying simulate buckling. I started from beam model using BEAM3 element. I did eigenvalue and non-linear analysis (the results are good, I sure because obtained results are similar and probable in both analysis, besides I found tutorial in internet to do this). Then I tried did this...

ok i understand. thx

so there is no possibility to mesh 3D model using shell elements to make faster calculations, meshing...??

Hi, Could somebody explain me why when I mesh solid model (volume) using shell elements I recive improper mass of the model?? It is becouse I enter improper values of shell thickness at nodes (TK(I), TK(J), TK(K), TK(L)) ??? How defined thickness at nodes for solid for example 100x100 and...

Thanks it work but... not exacly. There is another problem, my model is windmill blade where Ansys see exterior surface as area, and bear beam and ribs inside as volume (one volume) and there is no connection between area and volume. It`s impossible to connect them by merging lines or keypoints...

You`re right, I think that program treat my model as independent surfaces. I did modal analysis and I saw that some surfaces was outside the model. What should I do to delete this effect??? About modal analysis, the following frequences are increasing.

Force is OK, I tried calculate it also for gravity loads, the same: value at node is greater than current limit 1000000. I enclose file with pipe in attachment.http://files.engineering.com/getfile.aspx?folder=3daf4644-8c77-41a5-8898-6cdb5c9fab53&file=pipe.db

Ok lets simplify model to simple pipe which was created in SolidWorks, saved as .IGS and imported to ANSYS. Element type is SHELL93, then I go to real constants, material properties, mesh, displacement- one end constrained on the second end I apply force and run the solution (static). After few...

Hi, I have quite complicated .IGS model imported from SolidWorks. I meshed it using Shell93 element. And during the solving process I have error message like this: The value of UX at node 18556 is 1.061435247E+11. It is greater than the current limit of 1000000.This generally indicates rigid of...
