[problem] Loop into pold block to excite multiple elements 回答済み

Hi,

I`m trying to apply the same load function to 3 consecutive elements. With the code below I can produce the expected result.

plod

pdef ptx func

symb element = 1

symb element2 = 2

symb element3 = 3

matr dir1 etx$element out

symb iend = 2 * $element + 1

symb ibeg = $iend - 1

sdef ptx dir1 $i$ibeg $i$iend $j3 $j3

matr dir2 etx$element2 out

symb iend = 2 * $element2 + 1

symb ibeg = $iend - 1

sdef ptx dir2 $i$ibeg $i$iend $j3 $j3

matr dir3 etx$element3 out

symb iend = 2 * $element3 + 1

symb ibeg = $iend - 1

sdef ptx dir3 $i$ibeg $i$iend $j3 $j3

end

I`ve tried to write it in a loop as follows:

do loopI I 1 $multielements 1

symb element = $I

matr dir$element etx$element out

symb iend = 2 * $element + 1

symb ibeg = $iend - 1

sdef ptx dir$element $i$ibeg $i$iend $j3 $j3

end$ loopI

end

And the simulation shows an excitation along the 3 elements instead of the 3 individual elements:

I think the “dir$element” wasn`t creating a new name for the direction but I`m not sure. Can someone help me to understand what is wrong if my loop ?

Best regards,

Ray
