Dear all,

I would like to release a new version of OpenGeoSys with some minor changes:

- new Bishop model type

- thermal fluid expansion within Richards

- saturation and temperature dependent thermal conductivity solid

- bugfix Richards: neglecting storage from dp/dS in the saturated case

- small changes in order to allow the use of some material models within Richards flow model (Yaws viscosity, p-V-T tables)

- new input possibility for the base heat diffusion coefficient (Richards model)

If there are no objections I will update the trunk within this week.

Best regards

Jobst
