Dassault Systèmes welcomes Safe Technology!
We're very pleased to announce that Dassault Systèmes has acquired Safe Technology, Ltd., the developer of the fe-safe durability simulation application suite.
Even if you haven’t used their products, you’ve probably heard the name – Safe Technology
has been a partner of ours for over 15 years, providing a fatigue
solution to Abaqus users through fe-safe. As an add-on to Abaqus/CAE,
fe-safe uses proven techniques to accurately determine the fatigue life
of metal components under complex cyclic loading. fe-safe combines

Heat transfer solver?

Dear colleagues,
I would like to ask you about heat transfer solvers, but first i have to descirbe my problem:
I would like to solve some small case: a simply supported beam (or any other structure), exposed to uniformly distributed load (or any other type of loads) and fire conditions (i.e. heat transfer: steady-state/transient, linear/nonlinear) = complex analisys of such case - structural cases.
And now question:
Which solver with user-friendly interface or without could you recommend? What about free software?
Frictional rolling contact model CONTACT version 13.1 released
Dear all,
Herewith I want to announce the release of the frictional rolling contact model CONTACT version 13.1.
The main changes with respect to earlier versions of the program are as follows:
Abaqus works well with fortran90????
I know this question is a not new one and it has been posted before. But these posts seems not completely answer this question. I tested for77 and for90 codes for isotropic elasticity respectively. The analysis based on for77 codes runs successfully and the for90 codes can be compiled successfully. However, the analysis based on for90 codes shows the following warning:
(ansys) why can't I get contact result if bulk material is defined by usermat?

hi everyone:
I tried to perform a cohesive zone analyse in ANSYS, followed the turorial in HELP file. I used contact element to model cohesive zone. I found out that:
1, If I use standard material of ansys to define bulk element, like defined by 'mp,ex,1,2.1d5' or 'tb,biso', I can get a reasonable contact result;
2, If I use usermat file to define bulk element, 'tb,user', then the solusion also is done, but the resulte seems not correct, two part of model are not contact, some sections of them are coincide.

Abaqus - prescribe surface radiation

Dear all,
I have a problem assigning surface radiation to my model. Lets say the model consists out of two same size cubes. I want to simulate one cube sliding on top of the other. So lets say in the beginning the lower cube is covered 50 % by the upper cube and at the end it is covered 70% by the upper cube. Hence, at all times a part of the surface of the lower cube is free to the environment and another part is covered by the upper cube. However, due to the sliding process the free surface is changing in time.
