Title: why i can't see mesh?
Post by: halleluja on September 19, 2019, 01:49:39 PM

Hi everyone,

i have a mesh data file named mesh1.dat, you can see it in attachment. If you use

Code: [Select]

plot,node, you get a picture as plotnode.png in attachment. But if you use

Code: [Select]

plot,mesh, you can't see the mesh, which should looks like the picture plnodeparaview.png.

Can anyone help me and tell me why?

What version of the code are you using. 

Is it a FEAP element or your own?

Did you check the correctness of the mesh using she solut8ion command: CHECk?

Thanks a lot for your reply, Prof. R.L. Taylor.

It's Version 8.5 and i used my own element. I try to use a FEAP element now and it works. Miracle？
In attachment there are information from check and i get the mesh using FEAP element. Can you tell me why?

My guess is you are not setting all the necessary parameters in your element.  Read the programmer manual on what you should set in the isw=1 part.   For plots there is a parameter 'pstyp' , if that is not the problem post your element and we can check it.

I cannot get your routine to compile for ver85 due to missing function. 

We do not recommend using the form of the implicit statement you specify, instead use

implicit    none

and then declare what type you want for each variable.  It is a little more work but saves problems later.

You need to read the programmer manual -- especially around pp 50 where the options needed for isw=1 are given.

Look for setting the 'pstyp' parameter.  I believe this may be the problem.   Otherwise send the missing routine(s).

Not also using the form: go to (1,2,3,.....) isw
is also no longer recommended Fortran form.  We do still have some due do difficulty in removing.  It will work but using more structured form may be better.

Sorry. You need to add matfunc.f to  directory ver85/program

Thanks a lot Prof. R.L. Taylor. I did as you told me and it works.
