Well use smaller elements, set more substeps.

Before you define the shell elements use the esys commando the set the element orientation.

You what to know the difference between Workbench Mechanical and Mechanical APLD? Well the solver is basically the same but the big difference is that workbench is more user friendly , and has a better connection with CAD. Workbench Mechanical is perfectly capable of doing complex beam analsysis.

Why is it not working? Do you have convergence problems? Be more specific.

Normally you need to set NLGEOM,on and apply an imperfection to the mesh/model. Than it will be a non-lin buckling.

Dear Also an option is to use the GETFunctions. Regards

What type of contact are you using? Frictionless? Are you appling the load in 1 step? Try to you set a number of substep to apply the load.

Dear This could be caused by the link elements. Try using 1 element in the cable. The link10 elements in this case are very flexible. Also use a initial strain in the link10 real. constant,this will also make you analyse more stable.

Dear The procedure you are describing is a non-lin buckling analyse. As you describe buckling in a nlgeom,on can only occur is there is a initial imperfection. This imperfection is often retrieved from the lin-buckling. But also often this is a know situation( product imperfections). Also good...

Dear smyth13 This can be done with exporting IGES or an ANF file from DM. Regards

Hi I also had problems with this but after some trial and error. The best way of doing this is using a Joint load--> Accelleration. So you need to define a Revolute joint to ground at the center of the tube. Regards Garry

Hi In Workbench this can only be done with using a snippet(Commando block). Make a named selection of the areas where you want to aplly the coating. Name them for instance Coat_Surface Something like this should be in the snippet *get,et_max,type,0,num,max et,et_max+1,shell131 mp,?,et_max+1...

Dear Rupika What you can do is decrease the number of results to be writen. Analyse Settings-->Output Controls-->Calculate Results at--> Equally Spaced Time Points. Otherwise you will need to increace the number of results with the /config command. Regards

Hi The tetra element should behave better under these conditions. Maybe you can try to use the STABILIZE command?

Hi Try using the Solid285 this is a more suitable element for this type of problems.
