Re: About wind speed to wind speed ratio

Dear Tim, Thank you for your answer, but I don't understand the "the calculation does not work because your z0 is too high" you mentioned. Except when the initial wind speed value is set at the height of 10 meters, the heights of the wind speed and the wind speed ratio map in Figure 4 and ...

Re: About wind speed to wind speed ratio

Dear ENVI-met, thank you for your advice. I created a super simple model area without buildings and nested grids to compare the wind speed ratio distribution map with the wind speed distribution map. The model related settings are in Appendix 1-3. (1) V0 = V1 * (1.5m / 10m) ^ 0.22, V0 is the initial...

Re: Formula of PPD

Dear ENVI-met,

Thank you both for your answers. Is the calculation result of wind speed in the four indexes of wind speed, temperature, radiation, and PMV more reliable when the temperature is below zero?

Best wishes,

Re: Formula of PPD

Dear Tim,

When the outdoor temperature is below zero, can PMV be applied as an outdoor thermal environment evaluation standard?
Thank you for your reply.

Best wishes,

Re: How to output a graph of multiple consecutive time points in Leonardo

Dear Tim, I guess the reason for the minimum value of the data range is -999, is it a rectangular building in the area, is it correct? If so, how do you quickly cut off the space occupied by the building in paraview? In addtion,I added a PMV distribution map of ENVI-met at the same time. The black a...

Re: How to output a graph of multiple consecutive time points in Leonardo

Dear Tim, I encountered a problem in learning paraview software. After I imported the NetCDF file, I found that the minimum value of PMV / PPD in the data range is -999, which is absolutely impossible, but the values of temperature and absolute humidity are relatively normal. What causes this? Best ...

Re: How to output a graph of multiple consecutive time points in Leonardo

Dear Tim,

I have understood that the step size setting is not a solution to the problem, I am learning about software ParaView you mentioned, thank you for your help.

Re: How to output a graph of multiple consecutive time points in Leonardo

Dear Tim, Thank you for your detailed answer, I will try the method you said. In addition, I would like to ask whether this method is feasible. If I set the step size to 720 minutes, the simulation time to 24 hours, and the start time to 6 am, does it mean that I will get 6:00-17:00, 18:00-5:00, tot...

How to output a graph of multiple consecutive time points in Leonardo

Dear ENVI-met, For example, I want to get a thermal comfort map containing 8:00 to 18:00. Is there any way to get it directly? Or does ENVI-met have the corresponding function to superimpose 11 pictures after outputting one picture every hour? Because I want to know the thermal comfort distribution ...

Re: Problems with the new version

Dear Tim,

I have a new idea. If you have no problem with the simulation after receiving the file, is it because I am using the basic version (4.4.4)?

Re: Problems with the new version

Hi Tim, After repeated attempts, I thought it might be caused by the naming of the newly created 3D trees. After all the working paths were named in English, I tried the following. 1. When creating a new 3D tree, I automatically generated the ID and name by default, without modifying it. 2. Only one...

Re: Problems with the new version

Dear Tim, Thank you for your answer. I have tried many times, but even after naming all work paths in English letters, the above error still occurs, and the new work path also fails. May I know where you changed to make the model operational? In addition, what is your ID and name when naming a newly...

Re: Problems with the new version

Dear Tim, Thank you very much. I suspect that there is a problem with my newly created 3D tree, but the simulation has not been wrong in the previous version. My modeling process is: 1. Create a new 3D tree in Albero; 2. Create a new area in Space and place one of the above trees; 3. Use ENVIGuide f...
