Apparently un-physical result from BC

Hi All, I've measured the salinity of the effluent from a sand column but am having trouble making sense of the results. The linear pore water velocity is 1.78 cm/min and the column length is 25.2 cm. With zero dispersion, this would lead to a transit time of just over 14 minutes. In the observed da...

Dirac inputs initial value problem

Dear STANMOD team and users, I am using CXTFIT to solve the inverse problem for a column experiment. If the boundary value problem is set as a 'Dirac delta input' there is only one parameter to set (the mass M). When setting the initial value problem, if 'Dirac delta initial distribution' is selecte...
