Hello:

 My name is Eric and I am working on my MS thesis project.  I have been tasked with analyzing a reinforced concrete column specimen in Abaqus and comparing the analysis results with the experimental measurements.  The column is subjected to cyclic lateral loading. 

Hello

        I am looking to get some pointers on manual meshing using ANSYS workbench. I am not happy with the automesh results I am getting. I would like to discuss one on one via email. I am a real user and not a spammer. Anyone willing to discuss?

Thanks
