Re: Resume writing of plt files

Hi, Sorry for the late reply as I haven't login for quite a while. I managed to solve the problem in 2 ways: 1. use tecplot new tecio MPI to write out szplt files in parallel 2. rewrite your subroutine to send all data to one procs to write out a single plt file I think it's better this way, rather ...

Segmentation error when writing out szplt file with only 1 procs

Hi, I am writing a subroutine which outputs partitioned ordered szplt files. I rewrote a similar code in Fortran based on the example given. It is meant for using 4 procs. However, if I modified the code to use only 1 procs, I got a segmentation error. Using 2 procs works fine. So am I not allowed t...

Problem building with the latest tecio 142

Hi, My sch has the latest tecplot 2016 ex R2 and I want to try the latest tecio 142 with SZL. I managed to build my CFD code with tecio 142 in windows with VS and Intel Fortran. However, in linux, there's a lot of errors, both when using the supplied libtecio.a, libteciompi.a and also my own compile...

Marco to do interpolation on self created box for transient data

Hi, I have a problem as described in: http://www.tecplottalk.com/forums/viewtopic.php?f=16&t=5249 So I am trying to create a box (or rectangle) domain around the plate and use interpolation to transfer data from the global domain to that of the box. The problem is that my global domain is divide...

Create separate iso-surface regions

Hi, I have a plate which flaps about about certain center. In order to visualize its pressure contours at a fixed location from the center, I created a new variable called radius and used the iso-surface feature to create a cylindrical iso-surface 'tube', with pressure as its flooding parameter. It'...

Resume writing of plt files

Hi, I am using the tecio library to write out binary plt files. I'm using domain decomposition so each plt file writes grids for each processor. So if there's 100 procs, there's 100 files. each plt write the x,y,z,u,v,w,p for its own grids for the entire simulation time. now the domains get larger a...

Reducing mesh size for body

Hi,

I have a body mesh file, consisting of triangle elements. The mesh is too fine and I hope to reduce the no of triangle element.

Is there anyway I can do it in tecplot? Or outside of tecplot?



Thanks in advance.

Iso surface plot with artifical "lines"

Hi, I partition my grid in the y and z directions during my CFD run. The tecplot output follows the same partition. However, I found that when I used many procs (1000+), I got my Iso surface plot with artifical "lines" as shown attached. Do you know what cause them? Or how can I eliminate ...

Re: Write failure during repack on file

Ok, but there's really lots of space left during write. So maybe there's some problems with the hdd. We will test. Btw, I'm currently writing output sequentially in tecplot almost I'm running in parrallel MPI with each cpu having its own partition, and it corresponds to each tecplot file. So I'm wri...

Write failure during repack on file

Hi, I'm using tec v112 to output binary files in parallel (48 - 192 cores) from my CFD code. Recently, I kept getting this error: Err: (TECEND112) Write failure during repack on file 1. The result is that some files are corrupted and can't be used. May I know why this problem occur? It happens on so...

How to access color map in tecplot 2014

Hi,

May I know how does one access color map in tecplot 2014? It's no longer present, unlike in tecplot 360?

Thanks

Showing streamlines in 3D

Hi,

I saw this diagram below in a research paper. It shows the streamslines around a flapping wing, color coded with the velocity magnitude. I wonder if it is possible to achieve this using tecplot? What are the general steps? Thanks
