Iges vs box volume
I have just finished the rans tutorials. I wish to make some exercises.
I imported an iges file (a ship hull) from rhino. I created a box (i wish to simulate a towing tank test which we had done it last year) and used "translate" command to move the box like "wheel in a box" tutorial. I wish to substract the hull from the box so i'll use the wall condition on my iges form, and the box volume will be the water.
But when i use the subtract command Caedium crashes. I tried with a .step import but nothing changed.
Also i tried to import a subtracted box too but Caedium doesn't see it as a volume.
Can you help me to figure it out? If this is possible i will have a couple of questions like:
Can Caedium solve a free surface problem?
Can Caedium solve this problem with a free surface condition?
