software of interest to mechanicians
Hello,
MoFEM is open and free finite element code. See short video showing how easy you can install code form scratch https://youtu.be/6opfKER7JHA. MoFEM web page is avaliable here http://mofem.eng.gla.ac.uk. If you are intersted in contribute to MoFEM code or simply use it let us know. Feel free to aks any question.
I will keep my post brief to begin with.
The model consists of 7 rectangular interference fits (with 2 of the surfaces in direct interference). The model appears to be working perfectly fine at simulating the stresses induced due to the fits for a variety of mesh sizes. Once the mesh sizing of the slave components is reduced to below 0.4 the job fails due to experiencing negative eigenvalues.
To summarize - how can mesh refinement cause cause failure in a working model?
Hi everyone
is there any method to model the reinforcment as steel fibers inside beam element?
What is static riks solver?? Please explain in details.. As I am a learner of abaqus I get problem understanding some things, like arc length, increment in static riks etc.. I find that it is very useful for simulating collaps behaiour.. I wish to do a thrust experiment regarding geological setup... Please help and guide me..
Thank you

Hello,
I have to model finite number of springs with point masses on a soil layer in Abaqus representing resonators. I tried to use Reference Points on the soil layer and some Reference point above the layer and connect them with Spring/Dashpots using connecting two nodes option, I chose Line of action for the spring, then I add stiffness. In the next step I applied Point mass as inertia to the reference points above the soil.
Hi, I'm new user of ABAQUS. I'm trying to develop a model that involve one further output variable (the degree of cure of a polymer). I thought to use the subroutine UEXTERNALDB to write and read from an external file the array containing the values of this output variable in each element. But I couldn’t find out how to call this subroutine in the .inp file. Does anyone have any suggestion for my problem?
Thank you
Hello at all,
I have some serious issues with some of my models in Abaqus 6.14. I need to simulate shear failure to investigate the influence of concrete strength and fracture energy on the size effect. So far, everything went good. I calculated almost 100 models without any problem with exactly the same model (only materials changed). But: For the combination of concrete strength fck=50MPa and a fracture energy of Gf=60N/m or Gf=80N/m, the calculations will stop after a short time although the .odb file shows only some minor bending cracks in the beam
