Estimation of volume fraction of regions from DP Micress

Hi. I want to calculate the volume fraction of the red coloured region in the phase output shown below. These regions were created with DP Micress using 'operations'. How to calculate this?

Thanks in advance,
Deepu

Hi Deepu,

you can use 'operations' combined with 'properties' as a workaround.
Just perform an additional operation, like ( ( a >= min_val ) and ( a >= max_val ) ) ? 1 : 0 to set the interesting region to 1 and others to 0.
In the 'properties', you get the sum of all values (maybe an export of the new field is necessary before). Divided by the overall number of cells will give the volume fraction. Right?

P.S.:
The next release of Display MICRESS will include a better functionality for this purpose. However, that will be next year.
