AcuFieldView multiple datasets?

Altair Forum User

Hi - I'm trying to open multiple transient datasets of the same simulation in AcuFieldView. I have two .Log files that span timesteps 1-10 and 11-20 and I want to make an animation that includes both sets of data. However, when I try to sweep through them, timsteps 12-20 just look exactly the same as 11. I end up with an animation for the first half and then a static image for the second half. If I make the two animations independently I get the right results, but I'm left with two video files instead of one.

 

Is there something I'm doing wrong? When importing the data I used the AcuSolve direct reader, and chose append. In the transient data controls I then checked off 'Use Merged Times.'

When you use the Direct Reader (import using the .Log file) the process automatically creates Boundary Surfaces for you and you see those on the screen.  When you import the results via the FV UNS route, you need to create your visualization surfaces (Boundary, Coordinate, etc) manually.

I would suggest exporting .fv files from AcuSolve (using AcuTrans from command line or AcuOut from AcuConsole GUI).

There would be one .fv file for each of the time steps. AcuFieldView should be able to read this as a continuous time series dataset.

(Depending on the prefixes of Log files, you might have to rename the .fv files). I have not tried this, but this should work. Please post if this works or not.

I exported them as .fv files, and when I open them in AcuFieldView it treats them correctly as a set of timesteps. However, the data doesn't appear at all in the visualization window. I can change the timestep but nothing shows up. I'm not sure I'm importing the data correctly because it doesn't work with Log files either - only if I select the file in the launch menu will it read it. I opened the files by using the data input menu with 'replace' checked off.

How are the .fv files named? A screenshot of the folder with file details, might shed more light. 

If they are named case_ step000001.fv, case_ step000002.fv,... *010.fv,*011.fv,...*020.fv  then AcuFieldView would be interpreting them as transient for the same case and you would not need to load data twice.
