Please check the comment section of MAT1 and MATF1 entries.It is strongly recommended that only two of the three values E, G, and NU be input.
I guess in your earlier shared .fem file you are violating comment 7 of MAT1 card.
I remember in Freq Vs E table first entry start with negative youngs modulus which violates comment6 of MAT1 card.
So don't provide Freq Vs E & Freq Vs G value.Reading comments section of MAT1 and MATF1 should clear your doubts.
