problem of emission rate

Hi Dear all I'm using envi-met to study the effect of green buffer on particulate matters i use envi-met, at the same time i also did field measurement. but the result of envi-met and field measurement were different. It makes me very upset. the result of envi-met is 'green buffer> road > residentia...

Re: Floating point overflow and floating point division by zero

Hi, Tim Thanks for your reply. Now most my simulations working fine, but just one simulations still have some problems It is stop very soon after started without error message.(as the picture shows) Could tell me what is the reason? Looking for your reply, thank you best regards Tian

Floating point overflow and floating point division by zero

Hi, dear all it's me again, there are some problems in my simulation again. I'm doing a simulation about Particulate matter Pollution I want to simulate in four seasons. So i made four full forcing files for four seasons And use the same space model. simulation for spring and autumn done successfull...

Re: question about pm concentration

Hi, Tim Thanks for your help and the results of pm concentration are difference. But there are some other problems in my simulation :cry: Did as you say I make the emission rate bigger and it works. I set up simulation for 24 hours but error occurred at 8:00am, it said "Terminating thread 16564...

Re: question about pm concentration

Hi, Tim

the emission rate i used like the picture.
and i also tried to change the emission rate, but the results are kind of the same :cry:

Hi, Dear all There are some problems with my Simulation result about pm concentration. I run the simulation for 24 hours, but the maximum value and minimum value of pm concentration, The difference is very small. But it's not like this before.
