Contents |
MID |
Material identification number. No default (Integer > 0) |
BULK |
Bulk modulus. No default (Real > 0.0) |
RHO |
Mass density. Automatically computes the mass. No default (Real > 0.0) |
C |
Speed of sound. No default (Real > 0.0) |
GE |
Fluid element damping coefficient. No default (Real) |
ALPHA |
Normalized porous material damping coefficient. Since the admittance is a function of frequency, the value of ALPHA should be chosen for the frequency range of interest for the analysis. No default (Real) |
| 1. | MAT10 may be referenced by PSOLID entries with FCTN=’PFLUID’. |
| 2. | The material identification number must be unique with respect to MAT1, MAT2, MAT3, MAT9, and MAT10 entries, but may be shared with MAT4, MAT5 or MATFAT. |
| 3. | BULK, RHO, and C are related by BULK = C2 * RHO. |
Two out of the three must be specified, and the other will be calculated according to this equation.
| 4. | To obtain the damping coefficient GE, multiply the critical damping ratio C/C0 by 2.0. |
| 5. | This card is represented as a material in HyperMesh. |
