Once is done calculating go to the export manager tab, click on winair4/export model data, a new window will appear, type wind speed and select wind direction according to your site, check the three first boxes in the bottom of the window and then OK. The smaller the grid spacing, the more detail the results will be, but the longer it will take.Ĭlick CFD Cell Blockages/Perform Calculation/select covered in Z. WIND ANALYSIS PROCESSGrid tab/display analysis grid/auto fit grid to objects/select 3d airflow/and OK.Ī big grid appear, so I click adjust grid extents/manually adjust cell spacing (depending your needs click either option).
#ECOTECT SHADOW ANALYSIS FULL#
I made the grid a little larger than the buildings in it, using adjust grid extents/manually, and then to start the visibility: first I selected the faade or surface, Calculate/Spacial visibility analysis/selected objects and at the last step full 3D analysis grid. Now, Calculate/Solar access analysis/Incident solar radiation/current day/cumulative values/Analysis grid (use full 3D extents for analysis grid)/Perform detailed shading calculations, and then I choose 1pt and 10x10. I was looking for a calculation around the block, so I went for adjust grid extents/manually adjust grid extents, and then I choose a small grid spacing.
GRID SOLAR ANALYSISFirst display analysis grid/adjust grid to objects, choose around/selected objects/and OK. At step 6, under surface sampling: Low 1pt and for sky subdivision: low 10x10, and checked use fast calculation method. I tried specified period of time first but it was taking too much time, so at the end I selected the current day choice. SOLAR RADIATIONAfter reversing the normals, the faades were ready to calculate. SURFACE SUBDIVISIONIn order to have a proper faade calculation, I subdivide them first.Using: Modify/Surface subdivision/Rectangle tiles, and I offset them just a little bit. SHADOW DISPLAY & SHADOW RANGETo do this I clicked on: shadows settings tab/check daily sun path and annual sun path, and then click on display shadow or show shadow range for different shadow display.ĭISPLAY SURFACE NORMALSWhen I was trying to do the radiation on faades, I had some issues because of the direction of the surfaces, so I reversed the normals just in the surfaces that I wanted to calculate.
