right, it’s more understandable to end user.
can be keep hidden before implemented
is common only for the length, not the arrow
Well, I will add some kind of notice but negative values must be allowed to cover all directions so I will compose something else.
I will try adding “By selection” to the direction vector but it will have to be defined using two points and not an edge. Selection by an edge in this scenario is not yet supported.
No, the vector is important and needed. But the orientation of the vector is not needed. To explain, imagine a vector and then multiply this vector by a scalar -1. The vector now points in the opposite direction. But both vectors result in the same pressure field.
sorry i can not understand clearly. is this sign convention to defining pressure or suction in a face selected ? there’s available pressure input values can be use.
or may be for an option references to assign in local and global coordinate system.
No. Imagine a square surface that hydrostatic pressure is working on. Let’s say that the pressure at the top edge is 1 and that the pressure at the bottom edge is 2. Now the user has to select two points. One point at the top edge and one point at the bottom edge. In an ideal case, the user selects two points above each other. In this case, the pressure direction (depth) can be computed from positions of those two points. But the user might select the top left and the bottom right point. In this case the pressure direction cannot be computed from point coordinates. So we need a direction vector. This direction vector will define the pressure direction. And its direction can be up or down. Both directions will do since we defined the pressure values a the top and bottom edge. The pressure will increase from top to bottom no matter how the direction is oriented. Up or down.

Good job. Thank you very much for keep updating the software.
When you say, “Pressure direction” , you mean pressure gradient direction ¿isn’t it?.
Hydrostatic pressure will always be normal to the surface or is there room to also define that.?¿?
EDITED: Another question, sorry. Is the pressure corrected taking shell thickness into account?
Example: Thick submerged slab under hydrostatic pressure. ¿Is pressure the same at both sides of the slab or is it adjusted according to the deep.?
Yes, I was not clear in this regard.
Not at the moment. The pressure is computed at the position of the mesh nodes. Now that I think about it the shell section offset is also not accounted for. Hm…
Awesome, it looks really great

pressure type seem double, may the type ‘pressure’ changes to ‘Uniform pressure’.
alternatively it may left unchanged, and the ‘Hydrostatic pressure’ changes to ‘Hydrostatic’ only.
Of these two, I would choose the first version (“Hydrostatic” itself is too vague) but I still prefer the current naming. It’s the most intuitive one and seems sufficient.

I think I also like the idea of Uniform pressure. I will try it.
