I am using unstructured mesh for analysis. The number of points where I need displacement is high. So, rather than selecting or giving every coordinate individually, I would prefer to input all coordinates at once if possible.
The path is a good option to extract the data. Additionaly you can simply copy-paste the coordinates of point for e.g. Excel to Abaqus input table when defining the path. Each row should be a string in a form: X,Y,Z.
Dont go for un-structured mesh, try to get more command over ur mesh, more divisions will help u in it, Best wishes, Who is ur guide in SERC?
Sir, my guide here at SERC is Dr. S Vishnuvardan. I was modelling a notched beam so I doubt that I can go for structured mesh even if one can use structured mesh it will be difficult to get nodes of the mesh at predefined specific coordinates. I was interested in getting displacement at equally spaced points on the boundary of beam. The intention was to evaluate Stress Intensity Factor using Boundary Collocation Method.
I hope u may b knowing that I as Sct in FTL for 3 years, when DSRM was head and I also worked with Raghava & Gandhi Sir, and with My dear Pukazendhi. U can ask Vishnu or Pukazendhi more abt me. U Being from my own group and Based on ur problem, I can suggest u to create more divisions in ur model, and divisions should be a multiple of distance/ size u want to know the FEM results.
Thanks sir. I saw a paper by you in FFEMS where you had used structured mesh for C(T) specimen so I agree it is better to use structured mesh than an unstructured mesh in my problem. I'll mail you in case I need any help.
All I can say ,,,,,,,,,Due to the presence of crack , and due to the steep variation of stresses and strain, fracture problems required a special kind of mesh, and mesh discretization is also problem dependent , if u dont have command over the meshing , results are not reliable even the parameter calculation like k .
