- functionThe analytic solution to compare against
C++ Type:FunctionName
Controllable:No
Description:The analytic solution to compare against
- variableThe name of the variable that this object operates on
C++ Type:std::vector<VariableName>
Controllable:No
Description:The name of the variable that this object operates on
ElementH1SemiError
Returns the gradient difference norm part of the H1 error
The gradient of the variable is compared to the gradient of the specified function. Examining the error on the gradient can reveal excessive oscillations, highlight the need for a higher order finite element family, or show that the gradient of a known solution is well captured by the numerical solution.
where is the variable
, the function
, the norm exponent and the integration domain, which may be limited to certain blocks using the block
parameter.
Example input syntax
In this example, we compute a variety of error with the H1, L2 and H1-semi norms to verify that the H1 error is the sum of the L2 error and the H1-semi error.
