Try creating a reference point about the origin of that co ordinate system, then constraint it to the reference point of the roller.

Hi, I run the simulation on my computer and it seems to be finish without a problem. At each increment, the total iteration is 1 and no severe discontinuity, which i believe indicate no convergence issues. Am i missing something here?

I have attached the CAE, hopefully it will run without a problem. http://files.engineering.com/getfile.aspx?folder=3918623b-a5f5-43c0-8216-50cff09cbb43&file=Balle_de_golf.cae

Hello again , What i meant earlier is that the file run without any errors, because it sounded like you had problem getting it to run. I run it today and yes it seem to stop after a certain frame. it is because the time step was small and the rigid part does not reach the golf ball, and time...

Hi, Is the simulation not running at all? do you only get warnings but no error messages. Sometimes, you can ignore the warning messages but just be aware of them. I have just managed to get it the model you sent to run just fine. I got to say, i am not a expert in this field, but i have...

@compositesFEAguru I would like to get in contact please :). I wish to mention you in my acknowledgement, for helping me alot. Thanks

Not quite what I desired to get , but it is useful nonetheless :)

*Constraint

To my understanding from reading Abaqus manual about connecting the tie constre aint is that: If the mesh is the same as the parts and the cohesive elements, use the node tie constraint. If the the mesh is different ( finer for the cohesive element), surface tie constraint is to be used. What...

I managed to solve it :)...the problem was resulting from the partition on the cohesive element not being selected when I defined the surface tie constraint. I have a question relating to viewing the results.... It is possible to view the delamination through all the layer at the same time...

I spoke too soon.... The results I get from cohesive element are not good..the element gets extremely distored ( see the pic I have added, plz http://files.engineering.com/getfile.aspx?folder=cc8ca81e-bd55-4727-83f2-d1d61deb852c&file=Distorted.PNG ), and the delamination is rather odd ( I add a...

I have used conventional shell (2D) and didn't encounter any problem as I previously did. I have wanted to make that clear, just in case some else in future experiences similar error.

You are a guru indeed :)....it worked, like magic. You sir, are my saviour. I'm finally making some serious progress in my dissertation. Many thanks!

I have looked at the section you recommended reading...I modeled a 2D shell composite and defined the parameter for hashin and requested the relevant outputs (eg, HSNFTCT, HSNMTCRT,....) when I request a field output, the following errors causes the job to be aborted: Output request hsnftcrt...
