Re: Color map plot

Hi, unfortunately, there is no easy way to convert 1D data to 2D data. You have 2 options: (1) use the DSixOutputConverter tool to mirror the construction vertically/horizontally to get from a 100x1 to 100x2 grid (assuming you had 100 elements before). See documentation here: https://bauklimatik-dre...

Re: Kleine Bildschirmauflösungen

In den DELPHIN Einstellungen kann man die Schriftgröße global für das Programm verkleinern - damit passen dann alle Dialoge auf den Bildschirm, auch wenn die Auflösung nicht reicht.

Das kann auch bei Windows 10 und Skalierungsproblemen bei WQHD und 4K-Bildschirmen helfen.

Re: D6 Remote server setup

Threadripper is a good compromise between speed and money, so go for it. If you can afford it, always take the faster variant - turbo speed still is the dominating factor. Mind, DELPHIN parallelization benefits most until 6-8 Cores, after that the increase in speed is not as great (not all cores can...

Re: D6 Remote server setup

Hi Paul, I've uploaded the documentation, the server and client releases to our download page. https://bauklimatik-dresden.de/downloads.php (very far down at utiliities) I'll also edit the DELPHIN doc page later with some info on the Remote Solver Server functionality. A note on the queues: original...

Re: Heat radiation - how to handle

Hi Markus, you may not be aware of the "Long wave radiation exchange" model in DELPHIN (Field condition = source/sink model). You may approximate your pipe as a rectangle and then assign the LW field condition across the parallel air gaps. Also, you could just linearize the Boltzmann radia...

Re: Parameter values for Aw

Hi, ok, now I understand the confusion. Indeed, the Aw-value is reported in the material data sets primarily for comparision and evaluation of the materials. It is, however, not used in the actual calculation. The liquid conductivity function must be given in the material and Aw is just an additiona...

Re: Parameter values for Aw

Dear Markus, moisture transport in soil is a bit more complicated than in regular porous building materials. The composition of the soil (compaction degree) and stratification may be an important factor in your application. With respect to the Aw-value: while it is possible to measure this for certa...

Re: Cannot open "restart.bin"

Looks like a problem related to mapped network drives in Windows. Maybe also a virus scan software interferes... hard to tell. Does this also happen, when you store the project on the local harddrive?

Re: General issue with the CVODE Integrator module

Correct, a value of 1e-15 s is surely extreme (basically disables the check), and if indeed the solver takes such very small time step, there's probably something wrong with the parameters in the model. Even if the simulation is made to work with such small time steps, it is very likely that for lon...
