Quick Introduction of Agros2d, another open-source software

Great calculix 09, I followed with great interest all your tutorial on YouTube, and I used your program launcher Lazarus, Agros2D I knew him long before CodeAster and calculix, but with it I have not been able to model analysis Thermal non-linear in the transient, as currently the characteristics of the materials are constant and do not manage to change depending on the temperature. Correct me if I'm wrong, possibly any tutorial or explanation in this regard would be very welcome.
Thanks and good job

No, it is not actually true. You can use expressions like
37.5*(y+0.2)*(0.2-y)*((time<0.1)*time/0.1 + (time>=0.1)*1)
"Hole" example/
(with coordinates and time, etc). Also python scripting is available

To put the problem I explain what I do, and I state that I have already solved this problem well with SalomeMeca CodeAster and with the valuable contribution of a member of this forum (F.Renou) whom I thank, in practice I do the analysis Thermal 2D of a reinforced concrete beam subjected to fire curve ISO834 (EN 1992-1-2: Eurocode 2 Design of concrete structures - Part 1-2: General rules - Structural fire design) and cut both the heat map that an file with the nodal temperatures can rework in the next stage to determine the resistance of the beam to the design stress at the appointed time, after the prior downgrading of resistance of materials as a function of temperature, as from the above standard.
For thermal analysis concrete to change the temperature range of density, conductivity, (but Ownership physical and mechanical) and this must be taken into account during the transient thermal analysis.
On the other hand I would be more interested in developing such a thermal analysis with calculix, as prof. Guido Dondt had written to me that this possibility was already envisaged in its program, although Agros2D is easier to use.
Thank you
