GFEM V&V

What is the main objetive of FEM validation?

• $\alpha$ Guarantee the correct mathematical model

• $\beta$ Guarantee the correct physical behavior

• $\Delta$ Answers $\alpha$ and $\beta$ are true

• $\nabla$ Answers $\alpha$ and $\beta$ are false

What is the main objetive of FEM verification?

• $\alpha$ Guarantee the correct mathematical model behavior

• $\beta$ Guarantee the correct physical behavior

• $\Delta$ Answers $\alpha$ and $\beta$ are true

• $\nabla$ Answers $\alpha$ and $\beta$ are false

What are the managers needs from FEM V&V ?

• $\alpha$ FE models must be very accurate to take best results.

• $\beta$ FE models must be enough accurate to obtain useful results.

• $\Delta$ Answers $\beta$ and $\nabla$ are true

• $\nabla$ FE models must are enough accurate to take good decisions.

What can happen if no verification is performed?

• $\alpha$ The verification cost is higher than FEM poor results effect

• $\beta$ FEM results are correct

• $\Delta$ Undetected math issues could be present

• $\nabla$ All answers are true

What can happen if after verify FEM no validation is performed?

• $\alpha$ The validation cost is lower than FEM poor results effect

• $\beta$ FEM results are correct

• $\Delta$ Undetected math issues could be present

• $\nabla$ All answers are true

Is the structural test the only validation tool?

• $\alpha$ Yes, any other possibility is strictly forbidden

• $\beta$ No, could use other validated FEM for any structural design concept

• $\Delta$ No, could use other validated FEM for same structural design concept

• $\nabla$ Structural test never is necessary
