Hi Morten and Duncan, I think the main problem is the domain size of the project. unfortunately I cannot reduce the domain size as the wind farm is planning in the complex terrain site with four masts covering 16 -20 wind farm and neighboring wind farm of 5 project(300MW). I think the problem could be due to large domain with a 10m contourline interval plus spot-elevation. the domain size was prepared mainly targeting CFD model. so most probably you are right. but I don't think it is not a problem of Memory itself as we are currently using 16-32GB ram in personal computer. I think sonner or later WAsP should be run under x64. as it is still run under x86, so whatever the User has enought Ram, the program could not use the all available resources.

Dear Team, I am facing a lot of error message to calculate extreme wind climates, but I have no idea how I can use error messages. I have no clue how to report these error message. could you please guide me? / Could not perform the action requested because ... the 'Calculate a generalised extreme wind climate from 'MM24_Full at 79.0 m'' operation could not be performed because ... could not explore (or perform one of) the operations available for a selected thing because ... could not convert the OEWC to an REWC because ... failed to end a job on the progress monitor because ... the system reported that: 'Local exception: The job tag does not match the tag of the job on the top of the job stack.' /

Thanks for your prompt answers.

Dear Team could you please confirm these issues? 1) map size As I understand WAsP is based on "1:100 rule of thumb" to extend roughness map, and following the rule, the roughness size is normally considered 100 x Hub height. but now I found out in the WAsP best practices, it is written such as: / Size: map should extend at least max(150×h, 10 km) from any site – meteorological mast, reference site, turbine site or resource grid point / are there any reasons for this change from "100xHH" to "at least 150xHH"? 2) "standard height" of Wasp parameter I found out that since version 11.4 "Generalized wind climate default height range has been changed to 5-300 m a.g.l". does this mean that "tall tower profile issues" in WAsP has been validated including stability/extrapolation treatment? I could not find the validation report and I thought it is still under investigation. Could you please provide the reasons of changes? BR Gyeongil
