Evening to Everyone..

I'm trying to solve a dynamic diffusion problem using the PDEtool.

The study consists on taking snapshots to a pressurized cell, which contens a neddle with heavy oil (pendant drop) and CO2; i'm measuring the diffusion of CO2 into the heavy oil drop and one variable i'd like to determine is the diffusion coeficient (DC).

Using the snapshots, I could calculate the volumen augmetation and, with the equations (PDE's) of the phenomeum occuring, i do my math and calcule the DC. In order to do this, i need to import the image of the drop's edge into the PDEtool, and set it as my work domain. This image is a 480x600 binarized matriz (0 or 1).

Does anyone know how to do this? According to what I have read, vesion 1 of PDEtool does not allow to import geometry from CAD archives, but i do not know if this drop can be imported as an array.

I'm working on R14 (7.0.0.19920). PDEtool version installed is 1.0.4

Regards,

Rubén.
