Dear all, I am having difficulties in giving BC to 3D tube spinning problem. I want to rotate rigid roller around the workpiece (like nut travels in bolt). Also because of the friction between roller and the tube, roller should rotate around its own axis. I am successful in rotating roller...

I have used mass scaling factor of 1000. Still its taking long time beacause it is not using most of the memory. In my case, Abaqus/explicit is using only 200mb out of 5500 mb of available memory.

Thanks akabarten, but is there any other method to decrease computational time because the stuff I am doing will take a long time. I have heard about "running jobs on Grid engine".Is it helpful?

Hi all. I am running forming analysis on abaqus 6.10 on 64 bit platform with 8 gb of RAM. How can I give max memory usage for abaqus/explicit? There is a built in option for abaqus/implicit but for explicit there is no such option. I want to allocate max amount of RAM for the analysis. Please...

Can anyone tell me how to remesh any object in Abaqus/Explicit? What are the requirements for that?

Thanks abqMaster for the suggestion, but I have to use explicit because it takes less time for solving the problem.............Can you please tell me how to reduce excessive deformation in this problem?

I am doing explicit dynamic analysis of flow forming process which comprises of reducing hollow tube/solid cylinder's outer diameter using one or more rigid rollers. In that I have fixed bottom nodes of the cylinder and roller is given feed and rotational velocity around the cylinder so that the...
