ERROR # 1501 ***

Recommended Posts

Hello everyone,

 

I have a question about error 1501:  " for material id = 1 referenced from property id = 1. Either E or G must be explicitly provided for MAT1. Otherwise singular material is produced.".

I'm using solver Optistruct.

Could you please give me somes advices?

Thank you so much.

 

Best regards,

Lara

Hi Lara,

 

G or Nu will be calculated basd on input. If you remember of Solid mechanics E= 2G(1+Nu).

 

So you need atleast two parameters to calculate the third. If you furnish all three make sure they match with the equation :)

Hi Prakash, 

 

Thank you for your advice. :) I've just corrected the value of G.

Howerver, the error 1501 still exists.

Could you please give me some ideas?

Thank you so much.

Hi Lara,

 

Instead of giving all three you can just provide two material parameters. But make sure you enter atleast two parameters from E, G and NU

 

If you still get the error, please share the model file.
