5. Solution field storage

The CALC_ERC_DYN operator produces a result concept of the mode_meca type.

At each desired frequency, it calculates the solution fields \(u\) and \((u-v)\) which are stored in the following way:

For the th-calculation frequency, the following are stored:

in the (2 (i-1) +1) th num_order of the outgoing concept is stored the field \(u\)

in the (2 (i-1) +2) th number_order of the outgoing concept is stored the field \((u-v)\)

It is recalled that field \((u-w)\) is not calculated directly because it can be obtained by the scalar relationship:

\((u-w)=\frac{-\gamma }{1-\gamma }(u-v)\)
