How to change the number of significant digits in the exported near fields file in Altair FEKO.

I've tried absolutely everything and can't find any information. When exporting near fields (*.efe and *.hfe) the number of digits after the decimal point is always 8, I need to increase it to 16. In the settings of the solver I specified to save data with double arithmetic precision.

    Dear kirill_zeyde

    Under the General tab of the Solver Setting in CADFEKO there is the option to set the "Data storage precision" to either single or double precision. This option affects the numerical precision used by the Feko solver when solving the solution. For example, for electrically small structures the Method of Moments solver might need a higher numerical precision to accurately model the interactions between elements.

    This option does not control the number of decimal places in the Feko output files.

    It should be noted that the data in the *.efe and *.hfe files is written in scientific notation. This allows for the expression of both very large and very small numbers accurately and efficiently.

    The only situation where more significant digits might be require would be when you have field values that are reported as identical, but you expect them to differ with a very small difference that cannot be expressed with the available digits. Is this the case for you?

    Kind regards,
