Добрый день!
Поднял свой старый расчет фундаментов и занялся некоторой оптимизацией. Столкнулся с одной ошибкой "В экземпляре объекта не задана ссылка на объект" (см. скриншот):

moderator: external resource attached; please use the attach button if possible

Но код работает, хоть и ошибку высвечивает.
Ошибка в последней области "Определение вертикальных напряжений от внешней нагрузки и собственного веса грунта" файла "Ссылка на объект".

Смысл части кода, где ошибка, в том, чтобы осадка вычислялась только для слоев, слагающих вычисляемую сжимаемую толщу.
Возможно это следует записать по другому.

Сам файл
Ssylka na obekt.sm (322 KiB) downloaded 38 time(s).

Спасибо!

Сделал по другому:

Это просто не весь расчет (довольно объемный).
Вычленил из него только одну часть, естественно не всё учёл.

У меня в файле все нормально:

Может дело в версии программы (у меня довольно старая):

Не знаю почему у Вас возникает ошибка ... возможно действительно дело в версии.

Сделал так (выделено другим цветом и рамкой):
Ssylka na obekt2.sm (334 KiB) downloaded 30 time(s).

Ошибки сейчас нет.

here's a quick fix, to put right above the first error in the worksheet:

2018-07-23 11_18_30-SMath Studio - [Ssylka na obekt2.sm_].png

"cannot calculate" error message is triggered in the first line of the loop, by el(ξ,1):0.

The issue is due to recent changes in the policy of overwriting existing variables when assigning values by indices; since ξ already exists as scalar, you cannot assign values by matrix indices without redfining it as matrix or clearing it before.

Thank you Davide

I forgot to check it.

EDIT: But I still think there is an error in calculation - see my previous post. The if() clause was wrong. Only the last equation (from the three available) will be calculated because there is Форма_фундамента vector with three text elements. Therefore, logical expression Форма_фундамента = 1 has no sense. Moreover, variable r is even not defined.

I've seen it. Obviously yes, only the inner else condition will be calculated as it is the fallback for the always false statements before it; I assume there is an error somwhere, I'm waiting for further inputs by genf.

"Это просто не весь расчет (довольно объемный).
Вычленил из него только одну часть, естественно не всё учёл." в том числе и "r".
"Форма фундамента" не вполне актуальна в данном расчете, так как не учитывается практически (задел на будущее).
