    Could be any of about a bazillion things. You'll most likely have a problem in your model. Check the .f06 file.

    Illustrations in Mathcad

    I patch mine through Paint (the quality is plenty good enough). When you drop into Mathcad i'd recommend using: Paste Special - Device Independant Bitmap Its less buggy and doesn't slow it down as much (i've found)

    FEM-Stiffness matrix

    Some uni notes I found online: http://www.sv.vt.edu/classes/MSE2094_NoteBook/97ClassProj/num/midkiff/theory.html I would normally steer clear of wikipedia where possible. The notes above are ok, there's plenty more to be found online though (this was just a quick search). I'd recommend...

    displaying numbers in equations

    balazsm, For your example if you use a:=1 b:=2 c:=a+b explicit,a,b->1+2->3 (Where -> is the symbolic evaluation on the symbolic toolbar) By hiding the keywords and displayed evaluation as equal sign you can quite easily get what you're after c:=a+b=1+2=3 This is using version 13...

    Explicit Calculation

    Hi there, Sadly a simple solution never turned up. I've had to use a combination of two options. The first is as JulianHardy says above. The second achieves what I was after as far as the presentation of the report is concerned, however it involves using a little cheat which can really screw...

    Explicit Calculation

    If 'a' is a simple calculation as in my example, that is ok. However if it is a more complex calc, this becomes more of a problem. Is there a way of just showing the value of the variable 'a' and not it's origins? Thanks again...

    Explicit Calculation

    Hi all, In some reports, where variables have been stated earlier in the report it would be easier for those (other than myself) reading the document to see the values in the calcuation as well as the variables. Obviously this is as opposed to restating the values at the start of the calc (and...

    Help with Symbolics

    Hi all, I need to make some variables appear as symbols so I can get the answer in terms of them. When i make them symbolic however, it makes the whole matrix they're in symbolic, even though they only appear in two columns. How can I make the other values in the matrix normal? Example to...

    A general question on how to set the display of the number in MathCad

    Can't you just do; a:=100 x:=50 a/x=2 I'm a bit confused by what your asking if it is otherwise

    'Failed to save document'

    When i try to save my document Mathcad flashed up with an error message saying 'Failed to save document'. Does anyone know why this is happening? How can I get around it?! Is my document corrupted? (don't say yes) I have tried: 1) Save as a different file name (& different folder) 2)...

    Refer to calculated values at beginning of document

    It is often required for me to state some of the calculated values on the first page of my reports; at the moment i'm just copying the values into a table. The other day I nearly sent off a report with an out-dated value on the front page after I changed some of the report content and almost...
