Hi everyone,
I'm trying to create transition mesh like this in the picture, (please see the picture through the following link)
http://files.engineering.com/getfile.aspx?folder=22951696-9563-409f-97dc-ae98a2222a0c&file=Transition_mesh.PNG
I have used sweep mesh and transition mesh for the...
Dear all,
In my model I choose the units based on "kg--mass, nm--length, s--time",
so other units are
density--kg/nm^3
stress--GPa
conductivity--"10^-18 W/nm K"
specific heat--"10^-18 J/kg K"
Are these consistent?
Thank you!
Hi everyone,
I'm trying to do a contact simulation between a rigid body and a deformable plate. I used contact pair interaction. The job failed in the middle. I checked the .odb file, the plate didn't deform a lot, while the mesh changed a lot (I'm not sure if it's correct to describe it like...
Hi everyone,
I'm trying to analyze frictional heat generation between two surfaces. I realized that if I use general contact, there is no temperature change at all, but if I use contact pair, there is temperature change. Is frictional heat generation simulation only possible with contact pair...
Hi everyone,
Is abaqus available for simulation of nano scale structure contact? I did run micro scale structure contact successfully, but when I created the geometry at 10^-3 scale level of the previous one, and kept the units system the same (so it is supposed to be nano scale), I saw a...
Hi everyone,
I'm trying to do a simulation that a sphere slides on a plate, and meanwhile it moves toward the plate surface (like penetrating into the plate). However, it always fails at the beginning because of excessively distortion. After I improved the mesh quality, it can process further...
Hi everyone,
I'm running a simulation, whose mesh size is big and the element number is small. But it still takes a lot of time. Could it be due to the poor mesh quality of some regions? I didn't request data output very frequently.
Hi everyone,
I'm doing a simulation that a particle slides on a plane. The particle is a small part of a sphere, and its height is very small compared to the radius of the sphere. So it looks very flat. When I try to make very fine mesh, there are always some regions that can't been meshed, or...
Hi everyone,
I'm wondering if I can run a simulation with adiabatic option in the dynamic, temp-disp, explicit step. I don't see the adiabatic option when I create the step. And I tried to type it in the input file, but it doesn't work. Does anyone have the experience on this? Thank you!
Hi everyone,
I tried to obtain radial stress and hoop stress in a disk. But it didn't work after I created a cylindrical coordinate system and transformed the results into that cylindrical coordinate system. When I used tool--query, I still got the same numbers of S11, S22, S33, etc. When I...
Hello everyone,
I am doing a very simple model, a center fixed disk subjected to a concentrated edge load. However, I found out that even I change the material properties, the results will be the same. So I am really confused about this. Do you have any idea about how this happens? Thank you...
Hello all,
I am using abaqus on HPCC. The abaqus jobs always stop in the middle, and some files are lost. But I cannot find any error in the .dat file and .sta file. Also, I am sure that the run time has not exceeded the HPCC run time limit (48 hours). So what I am trying to do is to stop the...
Hello all,
I submitted an abaqus job to the HPC (high performance computer), but it cannot be analized because of some errors. I checked the .dat file, and it says that "ERROR: Unable to open the file <rank=0,arg_name=outdir>******.stt".
Abaqus on the HPC is just upgraded to 6.12.
Does...
