Isosurface showing different result than scalar scene

Hi, isosurface generated for my multiphase simulation showing different result than the scalar scene for volume fraction of water.

At the curved section, scalar scene showing water is striking the surface and then spreading but I can't see same in isosurface. I varied isosurface value from 0.05 to 0.95 but it's showing nothing at curved corner.

what could be the reson for this? Please find the attached images.

I am not sure that Isosurface is the right displayer for this.

I want to see how the free surface of water is developing in the pipe at different intervals of time. Isosurface displaying it satisfactorily but at the bend section of pipe, it showing nothing (No air and no water). Is there any other way to display it rather than by isosurface?

you can maybe try a derived part > resampled volume then create a scalar scene from that part.

no, that won't work for free-surface. i'm not sure what to tell you. maybe try logging a support case with CD-Adapco. They might be able to tell you why you aren't seeing anything in the corner with isosurface.

The isosurface doesn't show anything on the curved corner because you said the maximum you tried was 0.95. Looking at your scalar plot the value is clearly 1.0.

Thanks... it works
