Frew FAQs

Occasionally analyses obtain bending moments below the wall and very erratic results e.g. for total stresses
Is it possible to print all output stages at once using Frew? I've tried the 'batch plotting' but it only printed multiple copies of the first output stage
Analysis fails with "Vertical effective stress < 0" when using undrained pore pressure calculations (Frew v18.2 and earlier)
I’m doing a retaining wall calculation using FREW, and have come across an error when I am changing from short term to long term parameters (ie reducing wall and strut stiffnesses, and changing water pressure profile)
When we assign a Preload of 600kN/m to a Strut element at Stage 7, the program analyses and output a Strut load of 112kN/m only which is smaller than the Preload (600kN/m) at the same Stage !! Can you tell us how come the discrepancy between assigned Preload and the output Strut load?
Is there any way to estimate the maximum displacement of the wall under a horizontal load?
The passive softening option in the analysis method dialog box appears to be locked and cannot be accessed.
Frew "Watch-its" register
It has been reported that FREW did, in the past, overestimate displacements. Does this still remain the case and if so is there any guidance on how much this might be?
Analysis does not converge
I am using FREW version 18.2. Just want to know the way of modelling the change from undrained soil to drained soil in long term.
Changes to wall EI do not cause changes in deflection or bending moment
We have one query about how to input the strut under prestress condition. Is the strut stiffness equal to 0 in different excavation level?
I want to paste a bitmap image into my Frew file title block. I have tried saving the bitmap as all of the available options in Paint (I see the help file says RGB but I don't know which one that is) but when I click paste nothing happens. How?
