exec fail(mhk_wave): The wave conditions at timestep0were not able to be located in the power matrix. Please check your resource file
Simulation mhk_wave failed :exec fail(mhk_wave): The wave conditions at timestep0were not able to be located in the power matrix. Please check your resource file

Hi Juan,

Please attach a copy of the .csv file you are using for your wave resource data if you would like me to help troubleshoot.

Best regards,
Paul.

Hi Paul,

Thanks to the help the .csv that have the name of San_Andres_WEC is the one with the error and also I send you the .csv of the Wave Resource (lat12.63_lon-81.63_2020.csv) that is the complement of the .csv of the WEC

Hi Juan,

Thank you for sending the files.

The frequency of occurrence "San_Andres_WEC.csv" file needs two header rows above the resource data rows. In the attached "San_Andres_WEC.csv" file, I added those rows with empty data to get SAM to recognize the file. You can use a zero for any headers that you do not have data for.

The time series "lat12.63_lon-81.63_2020.csv" file needs time stamps from January 1 to December 31. For example, for three-hour data, the first time stamp might be 2013/1/1 0:0 and the last one 2013/12/31 0:21. The time stamps in your file start with 2013/6/1 0:0 and end with 2014/7/19 0:0. There is also one extra row in your file: For three-hour data, the total number of rows including headers should be 2923, your file has 2924. Perhaps you could rearrange the data to start with January 1 2014 and end with December 31 2013.

Best regards,
Paul.

HI Paul

Thanks for the help but I have a question about how the WEC is built since the document they provided me did not work for me although I managed to deduce some things and built another one which will no longer generate an error, even so I am going to send it to you to see if Help me to have more data or see if you can explain to me through a report or a message what the construction of the WEC file is like.

Stay tuned to your comments.
Best regards,
Juan Diego.

Hi Juan Diego,

You can find a description of the marine energy resource file formats in Help: samrepo.nrelcloud.org/help/weather_format_csv_marine_energy.html

You can also find examples of the files in the 'wave_resource' folder your SAM installation folder ('C:/SAM/2017.12.23' by default in Windows). For examples of time series wave resource data, see the 'wave_resource-ts' folder.

The file you attached is missing the first two header rows. You can copy and paste those rows from one of the files in the 'wave_resource' folder.

Best regards,
Paul
