The ANSYS R19 release has been out for nearly six months now, but the R19 App store has been opened for a couple of weeks only. We were waiting for it to be able to post two new apps developed with SimuTechGroup.

**Tangential Varying Pressure**: in Mechanical the standard Pressure load enables the user to add a pressure that varies along one direction, but not when it is a tangential pressure.

That’s the reason for creating such a feature with ACT.

**Time Dependent Hydrostatic Pressure:** the standard Mechanical Hydrostatic Pressure does not permit any variation in time of its value. But you may have to consider free surface level variation when simulating:

- changes in the level of a tide against a structure,
- rise or fall of water level in a tank or against the face of a dam

So was this feature created with ACT.

### Common Point: ACT Load Visualization

These two objects create a varying pressure, and we took advantage of the ability to visualize this variation before solve happens (which is better for sanity check).

Moreover, values will be changed automatically :

- if unit system is changed
- if current time value is changed in the Analysis Settings Graph panel (for the Hydrostatic Pressure)

Hydrostatic Pressure @ time 0.5s  Change Time  Hydrostatic Pressure @ time 2s

A future post will be dedicated to explain how we managed to do that.

_PS: By the way, the R19.1 is now available on the ANSYS Customer Portal._
