The summary of this step is that there is good documentation for the installation of STICS and SticsOnR already. SticsOnR & SITCS ON LINUX As noted, the documentation is already good. This is just some notes (mainly to self) about my experience with the installation of STICS and SticsOnR on a Linux (Ubuntu) system. My…

At first glance, by comparing the blockMeshDict files from the OpenFOAM.org User Guide, the blockMesh utility may have seen some changes. For the “Stress analysis of a plate with a hole” example, the mergePatchPairs command has disappeared from the dictionary. For the “Breaking of a dam” example, defaultPatch command has appeared. However, looking at the…

By my calculations, 2023 is a “normal” to “safer than normal” year with resepect to bolting risk. This, coupled with the general late sowing, means there shouldn’t be any general issues with bolting in 2023. Ädelholm had a sowing date of 7 April. Taking the station nearest – Alnarp – the approximate vernalisation hours are…

MODEL-it The symposium was the 8th International Symposium on Applications of Modelling as an Innovative Technology in the Horticultural Supply Chain. The name says the most of it. The website says the rest of it. The focus is post-harvest and food processing, but it seems to be mainly post-harvest. HIGHLIGHTS OF MODEL-it 2023 Presentations and…

OpenFOAM version: 9 Solvers: pimpleFoam and clampPimpleFoam v6 Case: clamp_22 GENERALLY QUITE WELL = NOT GOOD ENOUGH. Now that the model seems to work generally quite well, it’s time to start improving it. Here are some issues and fixes implemented in this step in the process. Deal with conduction at the boundary of the clamp.…

OpenFoam version: 9 Solvers: clampPimpleFoam (v5), pimpleFoam Case: clamp_16 IT’S ALIVE I’m not sure if this is the most elegant solution available within the OpenFoam environment, but to swap the inlet and outlet, simply, two different geometries are used. When the air is flowing left-to-right (ltr), the geometry with the inlet on the left is…

Feature image: A logo fitting of this project OpenFoam version: 9 Solver: pimpleFoam and clampPimpleFoam v5 Case: clamp_15 JUST ENJOY 35 hours of simulation using actual field data. I’m not going to ruin this moment by comparing the model results with the experimental temperature data taken from within the clamp… For reference, it took ca.…

Feature image: A clamp cover blowing in the wind. OpenFoam version: 9 Solver: pimpleFoam and clampPimpleFoam v5 Case: clamp_14 THE PROBLEM In the last post in this series, it was noted that there was an issue with dt being too small for this case. The proposed solution was to run the simulations in two steps:…

Case: clamp_13 (eg of clamp_13_05) Solver: clampPimpleFoam v5 OpenFOAM version: 9 THE ISSUE What the actual issue is, is actually not 100% clear, but some strange behaviours in the model have been observed and noted in previous posts. This is a summary of it: The change in the temperature of the solid over time =…
