Hello everyone,
I have been performing simulations using a tpfmm with time dependant study to simulate an EWOD pixel. For now, I made it move depending on a voltage variable I set as a parameter (so I haven't added the ES module). As it can be seen in the image:
But if I try to increase the simulation time more than 16ms, the limit when the liquid-liquid-wall interface point should change from the left boundary line to the lower one, it can be seen here:
I have tracked the liquid volume to see if it changes too much, and a 0.2% maximum change was obtained, so the problem won't come from an incoherent volume change.
I have also tried to reduce the mesh size and focalized it on the lower domain, yet it didn't solve the problem.
I have attached the mph file to this post.
Could someone help me with this problem?
