Hello,
I seem to have not received your email. Could you please send it again?

Hello,
Thank you very much, I will be looking forward to your email reply!

Dear Delphin-Team, I hope this email finds you well. I am writing to inquire about some issues I encountered while simulating the effects of air permeability on heat and moisture transfer in porous materials. When simulating the influence of air permeability in porous materials, I encountered a few ...

Dear Delphin team, Thank you very much for your answer! I switched off the check in the solver settings - see checkbox 'Use strict material function checks'. When I run the simulation, I get the error again. mwu(T) generation error: invalid mwu(T)=202.91 kg/m3 at T=-0.136343 C because monotonic incr...

Dear Delphin team, I have a question about the materials database. I chose Lightweight Concrete material for my study, when I clicked on the check button in the material editing screen, the "errors or warnings in material" dialogue box popped up, and at the Moisture storage it said "P...

Dear Delphin Team. Thank you for your answer, I have one more question. In the software help documentation, it is mentioned that a comprehensive description of ice treatment can be found in the paper: Sontag L., Nicolai A.; 2013. Implementation of an efficient numerical solution method to simulate f...

Dear DELPHIN Team, I am writing to ask a couple of questions related to the model: 1、Porosity Data: I would like to inquire whether the porosity data provided in the material database corresponds to absolute porosity or effective porosity. 2、Gas Phase Volume Fraction (θg) in the Presence of Ice: In ...
