Problem in Interpolating data command
 

I tried to read ip (interpolate data) file by using command file-->interpolate--> select file (ip.ip) in fluent but i get an error stating:

> Reading F:\E Drive\gambit&fluent\Pheumatic Conveying of Flyash\Case 3\New folder\ip.ip...
Variables for which data is found are following
pressure
mp-1
mp-2
epsilon-1
k-1
x-velocity-1
y-velocity-1
z-velocity-1
epsilon-2
k-2
x-velocity-2
y-velocity-2
z-velocity-2
Done.
Initializing values...

Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f

How could I resolve this problem??

Thanks & Regards

Perhaps run out of memory.

Thanks for reply..
Can be more specific as drive in which I am storing all fluent data has more than 80 Gb free space..

The interpolate data function need a characteristic structure, if one line is out of that there may be errors.

Example:

3 // Version of Fluent
3 // 3D-Geometry
800 // 800 interpolation points
4 // entries (pressure, temperature, phase 1, phase 2)
pressure
temperature
mp-1
mp-2
(0.0195 //now there are 7 blocks of 700 entries. First koordinats x,y,z and
0.0195 // then your values
0.0195
0.0195
0.0195
.......


I am interpolating 120.000 points and it works. Running out of memory wsn't a problem for me (64 GB Ram)

Can you please elaborate, I am not getting your point.
The steps i followed are exactly similar to those suggested in Fluent User Guide.
Step adpoted:
1.) Run the simulation for coarse mesh
2.) write interpolate file using command file-->interpolate-->write-->save (selected all variables)
3.) write boundary conditions using text command file/ write-bc
4.) read fine mesh using command file-->read-->mesh
5.) read boundary conditions using text command file/ read-bc (read same file generated at step 3)
6.) read interpolate file using command file-->interpolate-->read-->selected same file generated at step 2

You are firstsimulating in a coarse mesh and later you want to use a fine mesh, right?

- I did a similar operation a few month ago and it works good. Maybe your second and finer mesh doesn't fit to the data-file you are exporting.

Is it the same geometry in the first and the scond mesh?
You could check the mesh scaling and position, maybe this leads to an error.

- If you want torefine your mesh you can also do this in Fluent. The adapt funktion is able to refine a mesh without leaving the solver. Is this an option you could use?

Thanks Jim for replying

My two geometries are exactly same only difference is in size of mesh.

Yes I can use adapt function inbuilt in fluent for refinement of mesh.

Thanks..
