Error 953 - Not enough interactions specified

Dear All

 

I recently encountered the error from the picture, 'Error 953: Not enough interactions (total number) specified'.

 

I have had this error before without any actual problems in my simulation. However this time it seems that my simulation stopped calculating way before my prediciton area was filled.

I have a long and small prediciton area (1 m wide and 50 km long) but it stops showing values for received power or field strength after 1020 m. Is this just the limit for how many points ProMan can simulate? I have the resolution at 10m so it has the same amount of data points as my previous predictions which are shorter but at a higher resolution (for example 0.2m resolution).

 

Is this related to the error or do I have 2 seperate breaches of conditions?

 

Thanks in advance!

    Hello,

     

    there is no fix limitation in ProMan regarding the number of points which can be considered.

    The error 953 indicates that under the Parameters tab => IRT settings the number of (total) interactions (Max reflections AND diffractions) on the right is smaller than the number of reflections and/or diffractions defined on the left part of the settings dialogue.

     

    Best regards

    Dear Reinerh

     

    Thank you very much for the quick response. I do seem to have made a mistake in that part, great catch!
