HVDCFREQ,<num>,<freq>,[C1],…,[CX]

This command creates a list for coefficients that will be used with the HVD elements to create the imaginary component of stiffness matrices at each frequency. This set must be paired with a defined frequency referenced in the frequency argument. Adding coefficients works in the same way as adding frequencies to a frequency list using the FREQ command. The coefficient list will be created when the first HVDCFREQ command with a particular index number is entered. Further commands using the same reference number will have the coefficient list appended to the list already in memory. If HVDCFREQ command has no coefficients the coefficient list for that index will be cleared. The coefficient list will be paired to HVD elements by using the MSET command.

• num - index number for the C list
• freq - index number of the paired frequency list
• C1 … CX - double precision floating point coefficients that will be used with pattern matrices defined HDVP to defined the matrix used with the HVD element.
